Lightroom 5 Performance Issues?

Ever since Lightroom 5 has been released by Adobe, I have been actively using it and comparing with Lightroom 4. So far, I have only been happy with the new release and found most new functions to be both useful and well implemented. Our upcoming Lightroom 5 review is almost done and, for a while there, I thought it would be positive from start all the way through. But only recently I found certain troubling performance issues. These issues can either be version specific and thus affect all users, or it can be some sort of a local issue only present on my system.

Adobe Photoshop Lightroom 5

Firstly, I’ve experienced a slight slow-down when importing and exporting photographs. I have not yet made a direct comparison with Lightroom 4, so this may just be a false initial impression. I will thoroughly test this and write my conclusions in my Lightroom 5 review this week. What I did compare directly between the two versions is the speed at which image thumbnails are generated in Import window. Lightroom 5 is significantly more sluggish and takes several seconds to generate a few lines of thumbnails, while Lightroom 4 is almost instantaneous on my desktop. It is so slow, in fact, that it quickly becomes irritating.

Has anyone else experienced such a slowdown with the new version of Lightroom? Please share your experience in the comments section below!

    I agree the only troubles I have had come from the import issue and creating thumbnails. Other than that, everything else is working well!

      I’m having the same problem. The work around is to go down directly to the file list on the left, and click where you are importing form. Than the images appear very quickly.

        Since I’ve installed the release condidate 5.2, this issue is resolved. I also have not experienced any of the import/export or crash issues that some others have written about since installing this version.

    I’ve noted the same thing in regards to Importing, but I had assumed that it was because I am generating Smart Previews. Are you generating those? Those are bound to generate some performance lag, at least comparing apples to apples from LR4.

    Anyway, this is 5.0 so it is bound to have issues. It will be 5.1 or 5.2 before we can assume it is fully tuned. Which, will be just in time for LR6 :-)

    • July 2, 2013 at 5:11 am


      Smart Previews are generated once you actually start importing images. While you’re still in Import window selecting images to be imported, Smart Previews should have no effect on the speed at which preview thumbnails are generated.

      Lightroom 4 had no such issue, I don’t see why Lightroom 5 should have it – Importing isn’t a new feature, after all, it’s been there since version 1. Yet it seems I’m not the only one who encountered this problem. Bummer.

    I been shooting RAW+jpeg, testing fuji film simulations and I noticed that it some times get confused which one is the RAW file and which is the jpeg but when I go over it again it fixed it’s self it does appear to related to speed

    What I experience is not exactly a performance issue. Rather it is stability. I have noticed that Lightroom 5 (Windows x64 bit) has crashed several times since I started using it two weeks ago. With Lightroom 4 it actually never happened. The crash seems to have a random character, at least I was not able to find out a repeatable pattern yet.

    • 4.1) David
      July 2, 2013 at 5:36 am

      I’ve had the same – though each time no actual information has been lost. It seems to be related to labelling and sorting of photos – each time it’s happened as I have been paging through large albums in loupe mode (dancing fingers over the 1-9, p and x keys as I go).

      Generally I’m impressed – import might be a touch slower, but startup is faster (it was beginning to struggle with a 20000-photo catalogue on a mere Core i3/4GB RAM system), as is switching around inside lightroom in general.

      • 4.1.1) Fredroz
        July 18, 2013 at 12:02 pm

        Same problems with sorting, WinX 64 ..crashes,. Lags about 5 sec. to select a thumbnail, if I click on one and it lags I can hover over another one and it will select the second one. It refuses to move selected files for at least 3 attempts. However it does seem to work better working off the strip thumbnails below. When it starts acting up a reboot doesn’t help. Also there is a huge lag and jumpy mouse pointer when using the spot removal or clone tool. I have only LR open so computer overload isn’t the issue. I also have OnOne Suite 7 and have Lr AND, many other programs open also and that program works flawlessly.
        I had no issues with LR 4 but LR 5 is a great advertisement to NOT get a new release till the bugs are removed. It is driving me crazy so am going back to LR 4. Love the tools in LR 5 but not the crashes.

      I’ve seen somewhere on the adobe website a new DLL available that resolves the crashes on 64bits platforms. I think it was still in beta but someone posted that it resolved their issues.
      I can’t find the post I’m talking about but I’ve found this:

      July 2, 2013 at 8:54 am

      I am averaging a crash once every 1.5 hours of use. Usually it is when I am in development mode, but there has been no discernible pattern. The only good thing, I suppose, is that after waiting a few minutes, I can reopen with little problem. I am taken back to an earlier state of closing LR, but the changes I had made since the last closing are not lost.

    • July 2, 2013 at 9:12 am

      I can confirm this – had several crashes during the past 2 weeks, almost none with LR4 before. The good thing is that none of my edits were lost, but when restarting after a crash, sometimes it didn’t start where i left work off.

      • 4.4.1) Robert
        July 2, 2013 at 11:27 am

        Had the crashes as well.
        The solution I found via Adobe was to delete my preferences.
        I can’t find the guide right now but it did work. For the crashing.

          July 2, 2013 at 2:50 pm

          I had crash issues while culling the images, but went away after installing the new dll from the link above. Worth a try.

          • Robert
            July 2, 2013 at 7:16 pm

            Good to hear sooper.
            Mine crashed curing culling and in Develop. Completely random.
            Sometimes it’d be an hour, sometimes 15 minutes.
            Searches for me, at that time, didn’t bring up the .dll issue, rather a post from Adobe about deleting the preferences file then restarting LR.

    Are you using and generating the new Smart Previews upon import? If so, that would naturally take longer. I am, however, curious how the new patch tool will affect performance. The healing spot brush and the clone spot brush, if used extensively, on many images, always degraded performance of the entire catalog in prior versions, because each round spot required manipulating lots of pixel data while cloning over large objects, when displaying the final image and displaying each of the thumbnails. Because the brush circles had softer edges the larger they were, multiple clones over the same area were often necessary to clean up anything that wasn’t round like the brush, when trying to clone a crisp edge well in LR alone, without going into PS. This only compounded the problem! Supposedly, the new version has resolved these problems, but I am still sceptical!


    • July 2, 2013 at 8:33 am


      Smart Previews are generated once you actually start importing images. While you’re still in Import window selecting images to be imported, Smart Previews should have no effect on the speed at which preview thumbnails are generated.

    • 5.2) Peggy
      July 3, 2013 at 2:57 pm

      i bought LR5 specifically for the new clone tool as I have often wished for the one in LR4 to be better. I have not successfully fixed any problem with the new one yet. For instance in practicing on removing a long hair from a photo, all I got was a faded out spot that looked like a worm crawled across it.

  6. 6) Wayne Carey
    July 2, 2013 at 5:21 am

    I shoot my photos in RAW and I’ve noticed all of the performance issues you mentioned. Now… Let me ask you this. Are you also creating Smart Previews? I have only used this feature for testing and have noticed a huge slow down in perfeormance when performing this task. I thought it may have been my 2010 iMac but it looks like it may be a software issue.

    So far… I’m not impressed with the so-called performance enhancements, otherwise, I love the new features added to Lightroom 5.

  7. July 2, 2013 at 5:38 am

    Lightroom is so slow with importing that I use Bridge to get the images off the card, and then import into LR. Doing it that way is MUCH faster.

    It would be really helpful in your review, please, if you, or a reader, could suggest a way of ‘fooling’ LR5, on a Mac computer running OS10.6.8 Snow Leopard (or earlier?) that is in any case 64-bit, so far as I know, into ‘thinking’ that the OS is Lion or later. I know that it can be done with some other programs. As I commented before, many users are absolutely unwilling to switch to Lion, which immediately requires the replacement of several thousand £s’ worth of older software.
    Sorry to be off-subject here. Thank you.

      I’d like to try LR 5 on my Mac. But installing Lion or Mountain Lion just for that purpose is a no-go.

    • 8.2) Neil
      July 2, 2013 at 8:13 am

      It would only work if they aren’t making API calls that require Lion or above. But it would be an interesting experiment for someone.

      • 8.2.1) Graham
        July 2, 2013 at 11:35 am

        Yes, I found how to do it on a lesser program. Does anyone know whether it would work with LR5, or if that would wreck the whole computer? The instructions are clear, but I’ll never understand such things. Who would like to try it for the rest of us, safely?

        But What on earth is API please? !

        Open Finder
        Click on your hard drive
        Double click System
        Double click Library
        Double click CoreServices
        Right click (or Control Click) SystemVersion.plist and select copy
        Right click (or Control Click) on your desktop and select paste item
        Now open the SystemVersion.plist file from your desktop with your favorite text editor or by double clicking
        Now change the two places near the bottom of the file where they say 10.6.8 to 10.7.2. Your version may differ such as 10.6.x
        Click File->Save
        You will be asked to overwrite, select overwrite
        Right click (or Control Click) on the SystemVersion.plist file you just edited and select copy
        Open the window that you copied SystemVersion.plist on steps 1-5 and select Edit->Paste Item. (You will be asked to authenticate, select authenticate) and if you would like to replace the file. Select replace. Enter your password if it asks)
        Now go to the Mac App Store and select Updates
        Beside of iBooks Author, click update and let it update and install
        Open the SystemVersion.plist that you edited on your desktop and change what you did previously back to your original version. Example: change both instances of 10.7.2 to 10.6.8
        Click File->Save
        You will be asked to overwrite, select overwrite
        Right click (or Control Click) on the file you just edited and select copy
        Open the window that you copied SystemVersion.plist on steps 1-5 and select Edit->Paste Item. (You will be asked to authenticate, select authenticate) and if you would like to replace the file. Select replace. Enter your password if it asks)
        Now, Go to your Applications folder under your Snow Leopard Hard drive
        Right Click (or Control Click) iBooks Author and click Show Contents
        Double click Contents folder
        Double click Info.plist or right click (control click) and open with a text editor
        Search for 10.7.2 and change to your version of Snow Leopard, in our case 10.6.8
        Go to File in the Menu bar and select save

    I haven’t explored why yet but I too have experienced the import thumbnail slowdown. Very annoying!

    I feel LR 5 may be a little slower to import, but the difference is mild, but may simply be that impatience is increasing with age.

    Other than that, I find LR 5 faster than 4 on my MacPro 10.8.

  11. 11) Alex
    July 2, 2013 at 7:08 am

    I have the same import speed issues. Haven’t changed any habits from LR4. Win 7 64-bit, importing RAW off an SD. Very slow.
    Also mine crashes every time I exit. Actually pretty nippy on the whole though.

  12. 12) Craig
    July 2, 2013 at 7:38 am

    I haven’t noticed imports being slow because I “ingest” with Photo Mechanic and do my culling there. (Way faster than LR). I have, however, noticed my system comes to a crawl when I’m using the new content aware brush. Most of the time I can’t complete selecting the whole small area I want to remove before LR hangs. Very frustrating.

  13. 13) Stefan
    July 2, 2013 at 8:08 am

    Lightroom renders my previews extreemly slow. I don’t wait any more for them beeing created, I import them while they are grey frames because LR detects automatically the new ones. Until your post I thought it is a problem on my pc…seems not to be so.

    I have been having an issue with it crashing at start up. Then I have to reinstall LR5 to get it to open. Once open it seams to working fine for a few days. After I shutdown LR to run a backup, it crashes on start up. Anyone else seeing this issue??

  15. July 2, 2013 at 8:44 am

    Yes, I am seeing the slowness in LR5 too. And not just during import. For example, if I have previously worked on an image with the Adjustment Brush or Graduated Filter, and I re-open that image in Develop, it takes a long time for the previous edit pins to show if I am using either of those two tools.

    In addition, there is a very annoying freeze (most of the time but not always) if I select a published folder and then move to a different published folder. This requires shut down and re start to fix.

      I am having problems with the adjustment brush as well. It takes a long time, (way too long) to re-size the brush using the parenthesis keys. The brush fails to respond then it over compensates due to my hitting the key too many times thinking the program didn’t receive my prompt.
      Then I need to reduce the brush size then increase… very annoying.

      I have been very happy with LR5, until yesterday evening. I was retouching a portrait of a very nice lady who was wearing a black sweater that had LOTS of tiny white fuzzballs that didn’t seem to show up until my studio strobes went off. 60 or so Spot Removals quickly took care of those white fuzzballs. Then I turned my attention to the 20 or so stray “fly-away” strands of hair. Perfect time to try out the new Healing Brush, or so I thought…. After about 12 or 15 Healing Brush removals of stray hairs, everything slowed to a very slow crawl. The mouse pointer itself was almost non-responsive.

        September 12, 2013 at 3:18 pm

        the same here… opening LR5 works fine, but after editing a few pictures and switching between collections and modules LR gets incredible slow. It shows round 2GB RAM usage at startup and up to nearly 4GB after working a while. It sometimes (only twice) manages to clear some memory and RAM usage drops back to round 2.5GB and then it’s usable again.
        3.6GHz QuadCore and 8GB RAM on 64bit should be ok though…
        Are there any news about performance issues? Cant find anything but lots of ranting :(

  16. 16) Ryan
    July 2, 2013 at 9:45 am

    I heard about the performance issues, but did not experience it until I was doing some minor exposure tweaking using the Library module. When I tried this, my CPU maxed out to like 500% (multiple CPU/core) for what seemed like an indefinite amount of time. I restarted LR and tried again with the same result. I then went back to the develop module and it worked fine again. My takeaway is to not use the Library module for making edits until the next version is released.

  17. July 2, 2013 at 9:54 am

    Importing into my 2010 iMac is still slow, but I am using USB2, even though my Lexar card reader is USB 3 (Lexar CF 32g 1000x, SD Lexar 32g 600x, D800. CF Primary, SD Backup& Video) … so no noticeable speed decrease, hell it was slow anyway.

    But I have noticed that it does take longer to render my photos during editing than LR4 did, slightly annoying. It would be upsetting if I was ever under some sort of time crunch though.

    I have been using LR 5 Beta and now the LR 5 final version since some days and have not seen any downgrade in speed while importing pictures. In fact, overall I find that it’s faster than LR 4 in performance.

  20. July 2, 2013 at 11:17 am

    Yes I have experienced the Import problem with the thumbnails remaining grey for ages. I am not using Smart Previews. General performance has not been a problem however and much better than the performance issues I experiences when upgrading form LR3 to LR4. I have also experienced one sudden crash and shutdown which I don’t think I have ever had with Lightroom before but no work was lost and it was a only minor irritation. So far pretty happy with LR5 .

  21. July 2, 2013 at 11:24 am

    The previews punch up a bunch of grey boxes. I stopped waiting for pics to show and just import. That process seems to take the same amount of time. I end up importing a few more obvious losers, but they can be quickly X’ed out. Not a killer issue. LR5 does seem slow rendering full screen images using the “F” key even after the import/editing process is well over.

  22. 22) Heather
    July 2, 2013 at 11:29 am

    Yes, I’ve noticed it to be a bit slower but thought it might be my system for some reason. The other thing that I’ve had trouble with is the cropping feature. I will have cropped an image, gone on to the next and when I come back to that image, it returns to it’s original format size.

  23. 23) Robert
    July 2, 2013 at 11:30 am

    I have found it to be excruciatingly slow in a few areas.
    Moving to a new image can take quite a few seconds to load.
    Zooming in on images can often be excruciatingly slow.
    I dread to work with the adjustment brush or graduated filter because of how slow it is.
    This happens with files from every camera I have and it is not my machine.

  24. 24) Eric
    July 2, 2013 at 6:46 pm

    Thank you for bringing the topic. I started with light work on LR5 and didn’t have any problem. Since this weekend I downloaded hundreds of D800 NEFs: then started the issues. Even after import finished and 1:1 previews generation was achieved, I still have lag in the Development module. Sometimes it’s even like somebody is using my computer from remote, as everything is hung but then some fields that I didn’t select are chosen. I closed and reopened, restarted computer, optimize the catalog: that helped but still, sometimes, the Development module becomes quite unreactive.

    I work with a 2.8GHz iMac with 16 GB memory and a SSD: LR4 was fluid as were my intitial LR5 testing. That’s very strange, I may stop any development right now until the 5.1 comes out.

    • 24.1) Robert
      July 2, 2013 at 7:27 pm

      You’d think the file size produced by the D800 may contribute, Eric, but my experience shows to the contrary..
      Just returned from a trip and imported all my files from my portable HD to my desktop. Roughly, about 4,000 images from my D4 (avg 20mb) and 3,000 from my D800E (avg 47mb) – was in Yellowstone for a little over a month.
      On import, the D800 files went smoothly and fairly quickly.
      It was the D4 files that dragged.
      In reviewing, the D800 files load fairly quickly while the D4 files seem to drag; they certainly take longer than the D800 files to load.
      However, when processing, both are exactly as you describe; painfully sluggish. I’ve done all the things you’ve done. There seems to be a slight improvement immediately afterwards but after just a few images it’s dragging again.

      • 24.1.1) Eric
        July 2, 2013 at 7:36 pm

        Thanks Robert, but I really don’t think it’s a D800 issue: before on LR4 and initial tests on LR5 everything was fine. I don’t know if it’s the sudden increase in number of pictures in my library, while still modest with 30,000+ pics. All I say is: LR5 is buggy now and I can see that in the D module, even when the computer isn’t performing any other task.

        • Robert
          July 2, 2013 at 7:41 pm

          No, no…I agree with you.
          I don’t think it’s a D800 issue either. But, I have a feeling there will be those who will point to the D800 NEF file size and say that is a potential contributer.
          It isn’t and you’re right; LR5 is buggy.

          • Mike
            July 10, 2013 at 12:14 pm

            There are a couple of other variables on importing from those two cameras at least worth mentioning. Are you comparing importing when both are coming off of CF cards? Same speed CF cards? ..and using the same CF card readers? The D4 XQD cards are supposed to be faster than the fastest CF cards, but you also need to be using USB 3 connections on both to be getting similar speeds. On my system, the Sony Series S XQD and the 1000x Lexar cards run similar speeds when using USB3 cables. But both start out copying at well over 100/mbs and slow down to around 60/mbs after the first 40 or so files. I usually shoot at 14 bit on my D800 so my files are closer to 79 megs per photo.

            LR 5 seems to be slower on different people’s computer at doing specific tasks than on others. Mine is slow moving files from folder to folder and dealing with keywords and metadata while the rest is working about the same speed at LR4. The Develop module is working fine. My LR catalog has a little over 187,000 images now. I was asking questions about the catalog size back when I had around 80,000 and people told me it could handle a lot more.

            • Robert
              July 11, 2013 at 11:14 am

              Mike, you make a good point. However, in my case, this shouldn’t be an issue.
              Yes, I am using usb 3.0 for all imports. CF/SD (Lexar 32gb, 1000x/Lexar 32gb 600x) are imported through a Lexar usb 3.0 reader. The XQD reader is connected via usb 3.0 as well.
              Sounds like you’re shooting uncompressed while I am fine with lossless compressed hence a smaller file size.
              I rarely use CF in either camera as the D4 uses the XQD as primary and the D800E uses the SD as primary.
              In theory, given the cards I use, the D4 files should import faster, much faster. They don’t.
              But, the import speed isn’t a real big issue to me, it’s the incredible lag with the adjustment brush and sliders after editing just a few photos.

              As for catalog size…I took this into consideration and created new catalogs for my trip for each camera. D4 has it’s own with roughly 4k images, D800 it’s own with roughly 2500 images and I created a separate video catalog as well for all the video files.
              For me, moving files isn’t an issue. Nor are keywording or metadata changes.

            • Mike
              July 11, 2013 at 11:35 am

              Just for a test, try putting a Lexar 1000x CF card in your D4 and shoot a batch of photos with it instead of the XQD, then check the speed when importing them. At least in theory, they’d be just as fast importing as if they came from a D800. The mb/sec should be the same and the files per second should be faster than D800 files.

              I just added a Lexar 90 mb/sec SD card into my D800. Older versions were only 45 mb/sec, but I still assign the CF card as primary and the SD as overflow.

              I shoot 14 bit in the camera with uncompressed RAW files and process as 16 bit if they go to PS.

    Many years ago a wise systems analyst told me never to buy “dot zero software” … as in LR 5.0

    On the other hand, without the impatience of software and photo equipment gotta- have- it- now buyers , it allows the others of us to avoid buying until the time is right, i.e. when the problems are fixed…dot 1!

    Thanks very much

    Note: Dot 2 is even better.

      Yeah well, based on how Adobe slowly released upgrades to LR4 you may be waiting longer than you expect. Just go with 5.0 and deal with the little things until it is fixed, nothing is ever perfect.

        What do you mean nothing is perfect? My Nikon D700 is perfect!

        I may go to a Kelbytraining Live Session covering LR5 in August and see for myself.

    I work on a PC, my friend on a Mac. We have both noticed the same issue. When opening LR5, it takes forever to populate the folders on the left side of the Library. Hopefully Adobe will fix these slowdowns quickly.

    I have been using LR5 since its release and I share the writers observations. Though I can’t back it up with objective data, importing definetely ‘feels’ slower.

    My main problem however is with using the adjustment brush. When working on files, there is an enormous delay between moving the mouse and the following of the cursor on screen. Then it really stalls until finally applying the adjustment. And that’s just with applying one adjustment, say shadows or exposure!
    I’m pretty sure it’s not my PC, the specs are fine and performance with other programs, including CS6 is excellent. Maybe it’s still a little buggy, but I do really like this latest version of LR!

    I sure hope Adobe has a patch for us soon..

    I have a robust Windows 7 64 bit system with 12 gigs of ram and an approved video card. I’ve been using LR 4 all along and upgraded to LR 5 through the CC. It is up to date. I regularly let LR optimize the catalog and test the catalog for integrity. FWIW, my catalog has 187,000 images. My LR catalog is in a folder on the root level of my SATA D drive. I have Smart Previews turned off, previews set to Standard/Low, and it tell LR to delete previews after a week.

    I noticed very slow performance, mainly in the library module, when moving files from folder to folder and also in adding and viewing keywords. This is painfully slow now.

    I originally suspected my S drive was acting up, so I ran a disk optimize on it and did a registry cleanup in Norton. But, that doesn’t seem to be the problem. Outside LR, I can copy a folder of 50 t0 70 image files from one folder on the same drive in very fast time. I can also move them around in Nikon View NX2 at full speed, but if I am moving the same files in LR, I am looking at 30 seconds per image.

    Importing to the drive is about the same as before and most of the functions in the develop module are essentially the same speed. When I get ready do close Lightroom, I often get a message that LR is still writing metadata to the files. I never saw that in LR 4. Rendering previews in LR4 was never fast, especially on Nikon D800 35mpx files, but it is almost unusable in LR5. I now do initial previewing and culling in View NX2 before bringing them into LR for both D800 and D4 images.

    Everything I am seeing indicates this is a LR5 issue, but I am sure the large catalog is playing a part in the slow down.

  30. July 10, 2013 at 12:35 pm

    We’re finding the platform to be highly unstable with large files and have had very poor technical support from Adobe. In general, operating from the Cloud requires additional attention. My feeling is that Adobe is getting the cart way ahead of the horse and hanging the user with much more debugging responsibility. It may be a major data base problem (there is a functional problem running just one catalog and given our experience with collections, etc., I doubt anyone is doing it)–there seems to be a major error in trying to satisfy both Sunday photo buffs and also high end professional photographers. Having managed major data bases for government, I’m finding Lightroom 5 misses the data management performance pros should expect by miles. So, we’re running many smaller catalogs but our image file size (raw) is large, esp. with the Nikon D800 36.3 meg. The software doesn’t seem capable of handeling so much data???

    July 10, 2013 at 1:12 pm

    I bought the Creative Cloud to get all of the Adobe software, but of course that has nothing to do with how LR works when loaded on my local system. My hope is Adobe will address these issues and get an update out on the CC very soon.

    July 10, 2013 at 1:20 pm

    I am coming into this as an artist/photographer vs an engineer/programmer. I don’t care much “how it works” as much as “how well it works”. Most programs let you make changes to a file and then save the file when finished. LR never asks me to save my changes, so it “appears” it is adding to and adjusting the lrcat file constantly. At 187,000 images, making those changes on the fly may be asking too much of the engines that drive database? Maybe LR4 was getting sluggish and I just didn’t notice it as much as lately. I posted this here just hoping Adobe will see it. I posted something similar on the Adobe LR Forums.

    I’ve only been using LR5 for a few days (though I’ve been using LR extensively since the start). First impressions are mixed. First off, it crashes frequently when doing imports. I’ve allowed the online search for a cure. No luck there. It seems to be intermittent. It might (MIGHT) be associated with losing Internet connection. Weird, I know, but I experienced this when my connection was spotty and it seemed to resolve when the connection was solid again. Can’t explain it or why Internet connection is at all relevant It shouldn’t be, but who knows with Adobe software that seems to assume having an Internet connection all the time which is not true in my case. Take a look at the mess they made of off line help for an example of that. The people at Adobe who created that system are completely clueless, IMO. Secondly, imports are considerably slower. All things held equal comparing LR 4.4 to LR 5, I’d say 5 is about half the speed of 4.4. Not an official number, but it seems that way to me. Currently, I’m copying to my image library with Explorer then using the synchronize folder option when I go to bed or off for a snack or something. I can’t stand to look at it. I want the new editing features in 5, but at this point, my workflow is so negatively impacted by the flaws that I will continue to work with 4.4 and wait for a bug fix update before incorporating 5 into my professional work.

    Same problem with import and exporting file’s. I often develop picture’s for a time lapse sequence, so it take’s a lot longer. Very annoying!

  35. August 11, 2013 at 3:15 pm

    I experience delays, exorbitant CPU use (from 5% to 95% with one brush stroke), freezes and crashes EVERY SINGLE time I try to use the brush tool with the mask overlay checked.

    I’ve been using LR since 1.0. After testing LR 5 on small new catalogs with no problems I converted a 6,300 image production catalog. Under LR 4.4 navigating, selecting images and groups of images, adding keywords, etc. was very snappy. Speed never got in the way. LR 5 is terrible. I’m constantly waiting for it, it’s unusable. I’m going back to LR 4.4. This is the very worst, most disappointing LR update I’ve experienced. I’m on 64 bit Windows 7 platforms.

    Sounds like you and I are having a similar set of issues, though I stuck with LR5. I saw a note saying Adobe Labs has a 5.2 Candidate Release out, but I didn’t load it. I’ll wait for the final release.

    Since my original posts, I’ve noticed LR is sluggish during the initial writing to the database with additions and changes. Once it gets around to moving files, it can still do that part of the operation fairly quickly. This is most evident when moving a hundred or more images at one time. When trying to move only a couple, it just seems slow (or IS slow) because of the database overhead.

      August 13, 2013 at 9:02 am

      Thanks for your note. I agree that it appears to be the database perfroamnce. I can’t understand why they would’ve had to modify database engine or data schema to accomodate the new features that would’ve so drastically affected performance. I hope 5.2 fixes it so I can use the new features. I just can’t deal with the slowness of LR 5 when trying to cull and catalog adding many hundred images to a client’s catalog.

        August 13, 2013 at 9:21 am

        I modified my workflow a while back and it has helped speed things up a lot. I have one of the Nikon 35mpx D800 bodies that makes very large files. It takes a long time to render in LR. It was slow on LR 4.4.

        I found I could view the images first in Nikon’s own viewer–Nikon View NX2 and the images would load much, much faster. I use View NX2 to cull my images down to just the keepers and then import only those images into LR where I add keywords and other metadata. Life is so much better!

        I am not sure of Canon’s software.

        Good luck,

    I’m not at all happy with LR5… Love the new functions, a good start. I have been using LR4 for a long time and have had no issues. LR5 is a “DOG” in the full meaning of the word! It is SOOOO SLOW I can’t use it! I use it on two different PC, Windows 8, 64 bite, 8 gig of ram, no other apps running and after using it for 20 or 30 minutes at a time, it SLOWS down to the point I’m waiting and waiting and waiting for it to keep up with a simple adjustment function, erase is even MUCH slower. Also, the “zoom in” is SLOWWWWW to respond more waiting and waiting, and waiting. This APPS is fair from ready for prime time. Tomorrow I will call B&H to request a refund or credit. I’m staying with LR4 and you should also. I use raw files from a Nikon D800.

    Lee, you get 20-30 minutes out of it? I’m so jealous! I get about 8 before I have to force close it. It ties my computer up to the point where it won’t even close the program without the task manager… and even then it’s slow. And, I don’t have a weak computer. I’ve actually started to dread clicking on the adjustment brush…. and walking into my office has become a terror at the dread of waiting for it to open and load. lol It wasn’t this bad BEFORE the update.

  40. August 17, 2013 at 9:18 pm

    !@#$!@!$% I am so frustrated right now.
    Lightroom 5 crashes multiple times and the import is super slow. I am on Windows 7 64bit. Great new features, but why the performance setbacks? I have been using the picasa upload script, but it keeps crashing if I do stupid things like merely selecting photos to export. Feel like I want to send an invoice to Adobe for all the hours wasted due to their program that is not finished. They should have called it a beta or RC and not have released the blumin new version if it’s not complete and tested yet. WE pay for the product, so expect not to be beta testers. Just venting. I will contact Adobe and state my frustration. Wondering who will hear?

    I have this same issue and I’m quite frustrated with Adobe. It’s easy to see why end-users such as us just move on to other software since even their support won’t take care of the problem. This issue has been around since version 4, and they still haven’t resolved it three years later. Here’s a conversation I just had with their support, where they’ve obviously just given a quick fix solution and pushed me off the support queue again…
    You are now chatting with ‘Pritam’
    Pritam: Hello. Welcome to Adobe Technical Support.
    Pritam: Please allow me a moment while I look into your account & verify the details.
    Pritam: As I understand you are having issue with the working of Lightroom 5 as it crashes while launching,am I correct ?
    Pritam: Are we still connected?
    Christian: yes
    Christian: sorry on a phone call
    Christian: did you read my note on the issue
    Christian: hello
    Pritam: Thank you for the confirmation.
    Pritam: I will be glad to assist you .
    Pritam: May I have the serial number of the product ?
    Christian: one moment will get it.
    Pritam: Thank you for the serial number .
    Christian: ok
    Pritam: May I know are you contacting us from the issue computer itself ?
    Christian: yes
    Pritam: May I know since when are you facing this issue with Lightroom 5 ?
    Christian: Since it was installed, I had a different support ticket on this issue and it was not resolved previously.
    Pritam: May I have the case number please ?
    Christian: One moment, let me find it in my email.
    Christian: *******************
    Pritam: Christian, the first case number is for your Lightroom 5 purchase and the second case number is Lightroom 4 crash which was taken on 26th june as it was resolved .
    Pritam: Let us proceed with the troubleshooting of crash issue in Lightroom 5 .
    Christian: No, it wasn’t resolved. I called back in a day later and spoke to the same rep. I haven’t had time until today to get back to this issue, but it is now important to have it resolved since I am focusing on using Lightroom more actively, and with plugins – which have to be reactivated each time now.
    Christian: Please
    Christian: ready when you are
    Pritam: I understand that but your previous issue was of Lightroom 4 and now you are having issue with Lightroom 5 so we will proceed with Lightroom 5 crash issue .
    Christian: Its the SAME issue. Both lightroom 4 and 5 are crashing and I have to delete the prefernce file each time. SAME issue!
    Pritam: Please close Lightroom and all running applications .
    Christian: I have
    Pritam: Now navigate to Start Menu and then type %appdata%
    Pritam: You will get a roaming folder,click on it .
    Christian: have it
    Pritam: Inside the roaming folder ,click on Adobe folder .
    Pritam: Inside the Adobe folder ,click on Lightroom folder .
    Christian: ok
    Christian: ok
    Pritam: Inside the Lightroom folder , you will see a preference folder and inside it you will find a file as Lightroom 5 Preferences.agprefs
    Christian: yes
    Pritam: Please rename the file to Lightroom 5 Preferencesold.agprefs
    Christian: ok
    Christian: done
    Pritam: Now relaunch Lightroom and check .
    Christian: Yes, but the point is I have to do this proceedure ALL THE TIME.
    Christian: I works, then when I close Lightroom down, I have to either delete the preference file or rename it all the time. how do we resolve that so I don’t have to run through this every time i open lightroom?
    Pritam: Please relaunch again this time and check if it crashes or not .
    Christian: It does not.
    Pritam: Check two three times again and check if it crashing or not to confirm .
    Christian: It will!!!!!!!!!!!!!!!!!!!!!!!!!!!!! This is the problem. I need a resolution for this completely. Not just once then have to delete or rename the preference file again and again and again.
    Pritam: Christian, please try now to see if it does or not ,if not then the issue is resolved .
    Pritam: Or you can try by restarting the computer and check,I will keep the case as open,so that you can contact us back if you still face the same issue .
    Pritam: You will receive the case number at the end of the chat through email .
    Pritam: Is that okay ?
    Christian: The issue is not resolved. I already explained that I keep having to run through this same proceedure over and over after working with Lightroom, then I shut down and have to delete the preference file. Have someone call me at XXX-XXX-XXXX who can understand the problem and resolve it – with-out just giving me a quick fix.

    I went ahead and loaded the 5.2 RC from Adobe Labs and many of my issues with LR 5 went away.

    I was ready to jump ship and go back to LR 4.4 until I tried the RC version.

    Hope this helps others

    My old desktop bought in 2009 was running LR 4 perfectly. However, running LR5, my CPU often gets to 90%. For solving this issues, I assembled a new desktop. It solved the lagging issues. The CPU on the new PC never exceed over 60% (when exporting batch JPEGs)

    Old PC Configuration VS New PC configuration
    CPU Intel Quad Core Intel i7-4770k
    RAM DDR2 DDR3 at 1866MHz
    Drive 5400rpm HDD 128GB SSD Corsair Neutron GTX + 7200rpm HDD
    Graphic nVidia GeForce nVidia GTX 760

    My friend’s iMac also run LR5 sluggishly. My guess is the Lightroom 5 required much higher system configuration for the hardware.

  45. March 28, 2014 at 1:33 pm

    For me I noticed that this started after I had batch optimized lens corrections. When I unchecked lens corrections (and saved it for the LAST and final edit on an image) it sped up performance noticeably.

    I just bought a loaded iMac i7 (32GB RAM, faster graphics card, 512 SSD…) and Lightroom 5 is really slow – even after setting the Cache settings in File handling preferences. Lightroom is great software, but no reason should be this slow 5photoshop on the other hand is very fast)

    I recently “upgraded” to lightroom 5 on my MacBook Pro. AWFUL!! it crashes repeatedly, is slow, slow, slow. I have tried to export my photos from a recent trip to another computer, and the system just bogs down. I have now been waiting 4 hours to export my catalog with 2000 pics. Love the new features in lightroom 5 but it is unusable to edit, manage files, or enjoy my picture processing.

    I am ok with the performance except export speed wich is very slow. Paralel saving can be a very good feature.
