    Lightroom CC 2015.7 slower than death >:(

    coreym25318515 Level 1



      I've been using Lightroom since before the CC days and have always been very happy with the program until recently. While I fully understand that the program is progressing quite quickly and could potentially render some computers obsolete for the newer versions of the program, I don't believe that this could or should be the case for why LR is running so poorly. Following the previous update I was encountering intermittent moments of extreme bog down in the program that I was hoping would be fixed by the most recent update, but have thus far only encountered a further lack of usability. LR is struggling to import batches of photos, giving me the spinning ball of death when I simply try to access menus, taking no less than 4-5 seconds to switch between photos, and the same time over again to respond to any of the editing sliders, presets, etc., giving me the spinning ball of death or crashing often times when I try to enter into the develop module, god forbid I'd want the luxury of switching between photos within the develop module instead of the library!


      In short, LR is downright not useable.


      I'm no computer genius, but these are things I've done as of now:

      - I have turned off the Graphics Processor

      - Dropped JPEG preview sizes in general

      - In Catalog settings I have lowered both preview size and quality to the minimum

      - Have increased my Camera Raw Cache settings to 70gb (which seems ridiculous)

      - Have Optimized my Catalogs


      Things I have not done:

      - Turned off Sharpen, Lens Correction, Noise reduction for every photo (because I think this is absolutely ridiculous)

      - Consolidated all of my catalogs

      - Shrunk folder sizes


      While I've heard that these last items can sometimes help, I refuse to pay monthly for a program that is going subject me to the rage of such tedium, and I refuse to believe that Adobe is that irresponsible that they would make this program so power hungry and memory intensive that it would be too hip for a 1 year old computer.


      To either adobe or some interweb white knight, please help me make my photos sparkly and pretty before I set my computer on fire and throw an adult temper tantrum. I'd be eternally grateful for any help.

          - I have turned off the Graphics Processor


          Shouldn't be necessary for this machine. I have a similar but older machine and it is  faster with the GPU enabled than without in the last few major Lightroom versions.


          - Dropped JPEG preview sizes in general

          - In Catalog settings I have lowered both preview size and quality to the minimum


          This will have no real impact on performance. Best choice here is auto. Otherwise it will start redoing the preview every time you go to a new image. Having smaller previews will actually slow you down in this case.


          - Have increased my Camera Raw Cache settings to 70gb (which seems ridiculous)


          Also has very limited impact in my experience. There is very limited benefit of going beyond 10GB or so if your images are on a fast disk. What can help is to purge the cache once in a while.


          - Have Optimized my Catalogs


          That can have some impact.


          Make sure you are not doing something like face detection in the background. This will slow your machine to a crawl. Also check if your OS is not doing some reindexing in the background (check activity monitor in all processes mode to see if any process is taking up a lot of CPU.

          Have you tried resetting your preferences? See here: How do I reset Lightroom's Preferences? - The Lightroom Queen This can help in some cases when there is some corruption in those that can happen if you have had many major LR versions on your machine.

            I have the same feeling. After upgrade to 2015.7 my Lightroom is so slow that is impossible to use it, additionaly it is less stable than previous version - it hangs randomly when I use tethering.  I'm waiting for newer version

              Yup. Here too. Lag for a simple adjustment is about 4 to 7 seconds. It happened after the last update. Completely unusable. My photoshop CC works fine. I have to work in CapOne just to get work done. Really screwed here and I don't do all those things Corey does...

              because I just expect it to work, and I don't want to have to do some creative crap to make it so. I just need my software to work when it is downloaded.

                I had the same problem, and reverted to Lightroom 6.6.1, which is less sluggish on my computer (a Windows 7 machine). Maybe this is an option for you as well.


                The necessary steps involve removing Lightroom altogether, installing the "base version" 6.0 and then the update patch to version 6.6.1 (instead of 6.7).


                There steps are described in detail here: Lightroom roll back to prior update version


                FWIW, my GPU option was off before, and is still off. I could never get LR's GPU acceleration to work with the most recent version of the graphics card driver, and the only version of the driver that would work caused other rendering errors in Lightroom. Funny, but I've found that there was no actual improvement of performance anyway. It was just, shall we say, different.

                  it's a disaster for me at the moment. I use LR extensively for my commercial photography business and at the moment it's adding about 2-3 times the normal time to edit in the develop mode. Library module is fine but develop feels like everything is soaked in a thick goo that I can get through.

                  I really hope there is an update soon -  it's virtually usuable, but it's my go-to program


                  I expect better from Adobe. Professionals like me rely on the software and pay good money for it.

                    Two things that no-one seems to have mentioned as cures for slowness or stuttering in Library.


                    First is not to wait for LR to create standard previews in the background (while scrolling etc). Go to select your folder or All Photos, and then go to Library/Previews and tell it to create all standard previews (or even all 1:1 previews if you want them). Then have a coffee or go to bed (depending on how many images you have selected) while the new previews render.


                    If that does not cure the problem and you have tried all the other tips, it is possible that your previews and their databases are corrupted. I have just had that problem I think. LR started stuttering in Library scrolling (with all previews rendered), so I 'bit the bullet' and using my file manager (not LR) I deleted the previews folder (all previews folders and subfolders, and the previews.db and rootpixels.db which are in that folder). Do NOT delete your catalog!! I also purged the acr cache in Settings, because that may have got out-of-sync with the catalog or previews.


                    Then I reopened the catalog (110K images) and told LR to render all standard previews. That took about 3 days, so not something to be done when you need to use LR!!. You also need to stop it and restart LR each day or it slows down in rendering previews for some unknown reason.


                    After it had rendered the new standard previews and their databases (and new acr cache files and index at the same time), Lr ran perfectly smoothly again, better than I had seen it for quite a while.

                        Did you try reverting to version 6.6.1? It's what I'm using.

                          Thanks Bob. However, it's not really the Library module in 6.7 that is slow for me. It's most notable in Develop where really every control is rather sluggish. No such problem on 6.6.1.

                            The GPU performance feature is only meant to help those with 4 or 5K monitors. With 'lesser' monitors, it may slow things down. This may change in the future but for now if you haven't got a 4/5K monitor turn it off. It ought to be off by default since most people don't have these monitors which only seem to cause trouble of various sorts.


                            The develop module doesn't use previews; it generates a new image from the original or from your acr cache files each time you look at one, so no idea what your slowness is due unless you are using a 4/5K monitor when the GPU should speed up some of the sliders but not all.

                              I had the same problem when i upgraded to 6.6.1. I came across this post to see if 6.7 was any better. Apparently not. 6.4 works great for me. I haven't tried 6.5. I suggest revering back to 6.4 for now and start looking into other software alternatives like i have been. The new On1 photo Raw looks like it might be an option. Of course there is also Capture one.

                                Having same issue. Tried endless amounts of forum advice. Ridiculous that Adobe doesn't offer phone support "for this product" - the only thing I've found on this forum is ton more people with same issue from MONTHS AGO and no update from Adobe. Jaw dropped. Will have to go back to a crack copy that had no issues instead of my paid software!

                                  I have tried ALL of the things listed in this thread. It still runs really really slow. This is most apparent when using an adjustment brush. The lag is ridiculous - you can actually watch the adjustment crawl across the screen.


                                  I have a workaround which works a treat, but it does mean you will need to use Photoshop for the editing.
                                  At present. Lightroom is used only for browsing images - not for editing.

                                      My experience-

                                      LrCC2015.8  desktop Windows-10, 16Gb ram, Nvidia GT640 gpu.  With a fully installed Nvidia GeForce 'Game ready' driver bundle. (supposedly suitable for the GT640 from nvidia site download)


                                      After going to the Lr Book module- any book edit would take up to 60 seconds, or more, to happen. Right-mouse clicks would not even open the menu. Could not delete pages, could not even open the Lr preferences dialog. Scrolling was impossibly slow.

                                      Even closing Lightroom down and waiting, the operating system was still in a 'not responding' mode. Not even a shutdown menu from desktop would work. Task manager (took its time to open!) indicated that memory, ram and disk usage were all at a low level.


                                      I diabled nvidia drivers in device manager, did a complete un-install of everything Nvidia related-  Magic! everything back up to full speed. Lr Book and all.

                                      Windows-10 has shown a couple of changes, but has finally settled itself on a basic driver for the GT640 and all seems well with Lightroom now. May it continue so.

                                            I am having the same issue. Lightroom CC is unusably slow. I'm a professional photographer and have been using LR for years, so I'm am incredibly disappointed in CC (currently at LR 2015.8). Switching between modules gives me a beach ball. Using the spot removal brush is so slow that I can't do any sort of retouching work. In LR5, I could get multiple exports going at once (up to four with no problems), so I could get everything going, then walk away to take a break. Lightroom CC crashes if I try to do two exports at the same time. Those are just a few of the issues I've had, but just those are enough that it makes it unusable as a pro tool for me.


                                            I just switched back to LR5 because it's the only way I can get work done.


                                            Adobe, please, for $50/mo, I need tools that work!

                                                same here. fast i7, 32GB RAM, 8GB GPU, ssd's, yada yada yada and lightroom on my machine has become a complete dog. (actually, even when my dog pees on the carpet it's still better behaved the LR CC)


                                                tried a variety of graphics driver versions etc, use graphics processor on and off, and still just buggy laggy crashy.


                                                I'm on a super tight deadline - international brand ad campaign and its now running worse then ever before - has so far added several hours to my editing.


                                                Can't offer any possible solutions, and I better stop typing before the blood boiling rant takes over my keyboard.


                                                this will absolutely be my last job edited in Lightroom.  Sorry Adobe, I need software that is professional.

                                                  One more here.

                                                  Brand new Dell XPS15 with fast i7, 4K monitor, Nvidia Geforce 1050 GPU, 32GB Ram, ssd.


                                                  Lightroom is slower on this than on my 4 years old macbook air....


                                                  I am a professional who relies on LR for work, money, deliverable, clients. Barely usable now.

                                                  What is the fix, mr. Adobe?

                                                    Same thing here. Lightroom has been running slow for months but now with the new update 2015.8 release it is completely unusable.....


                                                    Here's my system info:

                                                    • MEMORY: 64 GB
                                                    • One SSD for the OS and apps, another SSD for the cache (100GB) and a regular hard drive for the photos


                                                    I'm a professionnal photographer and Lightroom is (soon will be «was») my work tool. Editing a job has become extremely long and painful. Adobe do something about it, we pay for a service that for now can't even use?!

                                                      I am not gonna repeat what everyone here has said already; facing the same painfully slow performance that renders LR completely unusable in any way, shape, or form!


                                                      What I can't get my head around though, is how adobe seems to completely ignore the calls of many many professionals who are not able to meet their deadlines due to the poor performance of this once golden software! They are not even taking their time to aknowledge and address their customers' concerns on these threads! This is crazy!


                                                      No wonder many of the photographers I know who once praised LR are jumping ships to competitors who seem more reliable at the moment! It seems that it would be a smart move for me to the same!


                                                      I hate it when companies take their customers for granted which adobe seems to be doing with their recent software updates :/

                                                          I posted to a new thread.


                                                          Slows down over time during session


                                                          The problem continues in 2015.9. on the highest-end equipment and all the latest software. Is easily replicated.


                                                          For me the slowness creeps in over time: after editing 20 or so photos it becomes noticeable and progressively gets worse. If I let it continue, I start seeing the screen go black on every function.


                                                          Quitting and restarting LR resets and starts this all over again.

                                                            I see several folks now reporting that this slowdown issue is related to having multiple cores/CPUs. According to them, the more cores you have the more likely you will see the slowdown. Ugh.


                                                            Some testers are limiting LR to 4 cores (in Windows) and reporting success.


                                                            Needless to say, this should be a priority fix.

                                                              I have a shortcut to LR on my desktop, and I altered the 'Target' line to the following. That only allows LR to use 4/8 cores, and the other 2/4 cores of my 6/12 core cpu are just available to the system and other programs.


                                                              C:\Windows\System32\cmd.exe /c start  "lightroom" /affinity FF  "C:\Program Files\Adobe\Adobe Lightroom\lightroom.exe"

                                                                For what it's worth, version 6.6.1 remains the last LR version that is stable and useful for me. 6.7, 6.8 and 6.9 all have the same issue - they're slow, start to lag more and more as I use them, and I eventually revert to v6.6.1 (2015.6). Something quite significant must have changed "under the hood".

                                                                  I tried this idea and confirm that this method does NOT seem to improve my situation.

                                                                  With testing I still see, even after setting affinity to 4 cores, the same behavior of performance degradation over time during a session.

                                                                    Lightroom is getting more and more useless with every update! I honestly have no idea what the developers at Adobe are doing!!! The app is degrading rather than advancing with every new update, it is ridiculous! I honestly cannot meet deadlines with clients due to its slowness... not only slower than a dying turtle but also it keeps freezing my machine as a whole every time i try to do anything whether in the develop model or  even importing photos in library to the extent that I am forced to either force-quit Lightroom or force-shut the whole computer to get rid of it! That is truly crazy! My computer is not the most recent piece of technology but And I find it ridiculous that in order to use this app I would need to keep investing in a newer more advance machine regularly!


                                                                    If this continues I am afraid Lightroom will no longer be the program of choice for many professionals who needs their gear, equipments and apps to be reliable every time they need to use them.


                                                                    What a shame!

                                                                        Close Lightroom

                                                                        Overwrite the preferences when prompted.

                                                                          • 34. Re: Lightroom CC 2015.7 slower than death >:(

I just updated (had been holding off for a variety of reasons) - WOW do I regret that.  I am now running 2015.9 and it's SLOW SLOW SLOW - no reason for this - paying $50 a month and trying to crank out work and it's REALLY becoming an issue - IS Anything being done to correct or address this - from what I am reading it does not seem so.

                                                                                    Unfortunately, this procedure doesn't seem to separate issues seen and/or squashed in various versions so it's highly inferior to the current issues pages that are available for After Effects and Premiere.


                                                                                    To add insult to injury, it doesn't appear that this slow down issue has been acknowledged at all, making this 6 months old thread and the offers I and others have made to more fully help document the bug, etc a complete waste of time.


                                                                                    If you ever get interested in knowing more about this bug, feel free to PM me.

                                                                                      I have the same problem. After 20 min of editing / several pictures edited, LR starts to lag more and more until it is unusable. I have to quit and stat it all over again.


                                                                                      First I thought CPU was throttling because of high temperature (5930K @ 4,4Gh) but Real Temp shows 37C when fans are at full speed.

                                                                                      I tried to run CPU at nominal speed – same problem.


                                                                                      Second I thought Samsung SSD 950 was throttling but installing dedicated fan didn’t solved the issue.
