    Lightroom CC is slow...

    boaz_m Level 1

      My PC specs are:

      Motherboard: Asus Z170-AR

      Processor: Intel i7-6700K (4.0/4.2 GHz Turbo

      Graphics: EVGA GTX 970 4GB SC

      RAM: 32GB, DDR4, 3000 MHz (2X16GB)

      Operating System: Windows 7, installed on Samsung 840 EVO 250GB SSD

      Catalogs stored on the SSD

      Photos stored on WD Black HDD

       

      I believe that this is quite powerful PC. However, I still experience slow down when working with Lightroom CC, especially after running it for a few hours. Restarting Lightroom helps for some time but then it slows down again. It is slowing down after merging to HDR for example (in Lightroom). It is also very slow when converting 20-30 files from DNG to JPEG at once. It makes everything slow, until the operation is completed.

      I have configured Lightroom the way I have learned to be the best:

      Use Graphics Processor - Enabled

      I generate 1:1 previews  and keep them for 7 days (Used to be 30 days - No difference)

      Preview quality: Low (It used to be High and the Medium - No difference)

      Standard Preview Size: Auto (1920px) - Same as my monitor size

      The files that I process are DNG, from a 36 MPX camera. Some are standard (50MB) and some are in-camera HDR (150MB)

       

      Any suggestions to improve the performance? Where do you think my bottleneck is?

          Hi boaz_m,

           

          Please refer: Optimize Lightroom performance also, are you using any NAS drive for storing images and Lightroom catalog?

           

          Thanks,

          Mohit

            ... you using any NAS drive for storing images and Lightroom catalog?

             

            Mohit,

            The catalog can not be stored on a network drive ..

              Exactly what functions in Lightroom are slow?

                Thank you all for responding

                Mohit - I have gone through the optimization last many times.... I don't use NAS for storage

                dj_paige - Here is my work flow. I shoot mostly real-estate.

                1. I import the DNG file to Lightroom (most files are around 50mb, some are 150mb

                2. I select the photos that I want to edit, mark them with 3 stars

                3. I do basic editing to each image (colors, light, adjustment brush etc.)

                4. Sometime I also merge to HDR. This consumes a lot of resources and after the merging is done, Lightroom will slow down significantly, until I restart it. Even going through the photos becomes a hassle.

                5. Most images don't require blanding so at this point I convert them to JPEG, and reduce the size to 4672 pixels. This, again, takes time (I didn't measure) and takes resources from the computer (CPU? GPU? RAM?)

                6. Some images require blanding in photoshop. A few sets of 2-4 images. I open them as layers in photoshop and save them to TIFF. This creates some 1GB files. I then convert them to JPEG and delete the TIFF

                7. After processing this way a couple of folders, with 20-30 images each, Lightroom slows down dramatically and I need to restart it, What slows down? Pretty much everything. Going through the images, editing some more. I often see a white screen for a few seconds, especially while Lightroom is converting about 10-20 files to Jpeg. But also after this task is completed, then re-editing some of the images can be really slow.

                When I look at the task manager, I see that Lightroom uses up to 3GB of RAM. Photoshop may be using 1GB and the browsers maybe 1GB together. So if I have 32GB then RAM shouldn't be a problem, right?

                So what is the bottleneck here? CPU? GPU? Me....??

                  1. I import the DNG file to Lightroom (most files are around 50mb, some are 150mb

                  So it would help if you talked in megapixels and not megabytes. What is the size of your images in megapixels? Ok, I see you said 36 megapixel photos, these are relatively large photos, which will require lots of CPU speed (and GPU if enabled).

                  3. I do basic editing to each image (colors, light, adjustment brush etc.)

                  This could be the problem. Using large amounts of brushing is known to slow Lightroom down. You have all the symptoms of the problem caused by lots of brushing.

                  5. Most images don't require blanding so at this point I convert them to JPEG, and reduce the size to 4672 pixels. This, again, takes time (I didn't measure) and takes resources from the computer (CPU? GPU? RAM?)

                  I guess this step doesn't seem necessary to me (and I also don't recognize the word "blanding"), and in my mind, this entire step is an unnecessary waste of time. However, anticipating that you have a valid explanation for why this is needed, the speed of converting to a JPG is entirely based on the CPU, and as I said, if you did a lot of brushing, it will take a lot of time.

                   

                  7. After processing this way a couple of folders, with 20-30 images each, Lightroom slows down dramatically and I need to restart it, What slows down? Pretty much everything. Going through the images, editing some more. I often see a white screen for a few seconds, especially while Lightroom is converting about 10-20 files to Jpeg. But also after this task is completed, then re-editing some of the images can be really slow.

                  Brushing! It slows Lightroom down. If you are doing a lot of brushing in Lightroom, this is most likely the problem.

                   

                  Instead of doing lots of brushing in Lightroom, do it in Photoshop; or if you must do it in Lightroom, turn off the GPU acceleration (Preferences->Performance->uncheck "use graphics processor"), do the brushing before you turn on the lens corrections and transforms, and if possible, get a faster CPU.

                    1. I didn't realize that brushing slows down Lightroom. I find it to be one of the most useful features in Lightroom editing..

                    2. Sorry, I meant "blending" and not "Blanding".. I used to open the DNG files in Photoshop, then edit and save them as TIFF (16 bit) and then convert them to JPEG so that I can deliver them to clients. But I found that opening 10-20 images at the same time works better if they are JPEG. But then I lose time by converting them all from DNG to JPEG. Converting from TIFF to JPEG seems to be working much faster and consumes less resources from my computer

                    3. Brushing in Lightroom is a lot easier than in Photoshop. I am assuming that you mean by applying the changes in layers and masking them out? How does turning off GPU help with brushing? Should I do ALL Lightroom editing BEFORE lens correction and transform?

                    4. Faster CPU? Is 4.2 not fast enough..?? What would you recommend? Is better GPU going to help at all? It is just easier for me to replace than a CPU

                    Thanks for all the help so far!

                        What do you mean? The HDD is not external. I store the images on internal HDD and the operating system & catalogs on SSD

                            3. Brushing is a lot easier in LR, but a lot faster in Photoshop! In Photoshop, the order of editing doesn't matter, as far as I know. In Lightroom, the speed of editing will be faster if you do the brushing without lens corrections and transforms, and then when you are done with the brushing, turn on lens corrections and transforms. Also turn off the GPU acceleration if it is on.

                             

                            4. Sadly, this entire problem is due to the way LR is programmed, and a faster CPU will help. Whether or not you want to pay for a faster CPU, compared to changing your workflow, is up to you. A GPU will not help with the brushing issue.

                              Honestly, is an i7 6700 slow? How much faster should it be?

                               

                              If any pattern is discernible in this, it's that the higher the machine specs, the greater the likelihood of speed issues.

                               

                              These suggestions to upgrade the CPU should stop. It's obviously not where the problem is. It will not get anyone anywhere, except maybe an unnecessary expense.

                                I agree. That CPU is quite powerful and should not be a problem. I run an iMac 5K with a 4 GHz i7 and find Lightroom plenty responsive.

                                 

                                But I don't use many, many brush adjustments. Maybe a couple or four. How many is "a lot?" How many is a problem?

                                  The problem could be Lightroom, but a faster CPU will chug through the tasks faster than a slower CPU.

                                    Of course. But how much faster than an i7 at 4 GHz is common?

                                      I don't think so, because the real problem is elsewhere. Not even the six-year old i5 that I use at home, ever peaks CPU usage, whatever I throw at it. And what I mostly throw at it is 36MP D800 files.

                                       

                                      My work machine, an i7 that should be at least twice as fast, is - well, not. If anything, it's a bit slower. Everything else is identically set up (it has to be for a number of reasons), including a single 1920 x 1200 display.

                                        The user is doing a lot of brushing, which is computationally intensive. The user has 36 megapixel originals which adds to the amount of computations that have to be done. I don't remember what size monitor he is using, but if he is using a 4K or larger monitor, that increases the amount of computations that have to be done. To deny that a faster CPU could do these calculations faster is not something I can agree with.

                                          Is there any evidence that the CPU is maxed out? Perhaps Lightroom is not CPU bound, in this case?

                                            So turning off GPU at what point? After brushing and before lens correction? Or turn it off completely? What is the logic behind this action?

                                            The CPU that I use is Intel i7-6700k and according to a bench test that I have read, only the Intel i7-7700k was faster, and by no more than 2-4% so I guess I will skip this for now..

                                              I will stars working as dj_paige suggested, brushing before lens correction and see how it helps

                                                I have never had to decide when to turn the GPU acceleration on or off, because I do not use GPU acceleration with my Lightroom. So, I leave it up to you to experiment with this, but I do know that GPU acceleration OFF will speed up brushing (as stated by Eric Chan, the LR developer in charge of programming, that's probably not his actual title but you get the idea)

                                                    You could close all the programs running except Lightroom and see how it works.  I'm using that same processor on a 27 inch iMac retina with 16gb RAM with the catalog, photos and previews on and external thunderbolt Lacie SSD and it works fine.  I usually have Safari and Mail loaded and occasionally Photoshop but close Photoshop when not needed.

                                                          No. I assumed that Internet browsers consume mostly RAM and not CPU or GPU, and since I have 32GB I thought it was plenty to handle all  - Lightroom, Photoshop, Chrome and Firefox

                                                            A possible cause for Lightroom slowdowns is malware detectors and antivirus software including Microsoft's malware detection software. Some rescan your entire catalog file every time a single change gets written to it. Trick is to exclude the catalog file and preview database from those scanners. Don't know if this is your problem but it's worth a try.

                                                              I have already tried. It is not the case..

OS on a single SSD (and assigned Adobe CACHE there), Database of lightroom on a separate PCIe Memory storage (more 12GB/s of transfer). All the images are on a 12x3TB SAS RAID5 Storage (for fast ready access). And dual GTX 1080 Video card. Editing only on 1440P on my screen.

I already saw (and this is history for Adobe) huge memory leak when using it. But even there this is not a problem, because have have plenty of RAM. I have even try to start with fresh Lightroom data without any sucess.

                                                                      Fixed!

                                                                      I wish I could find the all the places I have posted about Lightroom on large files and 4k being unusable.  I bought a couple of new camera bodies that are 30meg and 50 meg pixel sensors and have started shooting a lot of 4k video.  I could see that Lightroom was slower with the larger files (some 60megs), but I wanted to see the increase in clarity that I thought I should see.  So I bought a couple of 4k  (4096x2160), 99.9% adobe 1998 screens with 2 Nvidia 1070's.  My machine was a I7 2790 4 core with 32 megs of ram.    Although Photoshop showed me detail that I had never seen before on my HD monitors, LIghtroom became all but unusable. 3 seconds to spot heal or load a new picture. So many times, the screen would just blank for a couple of seconds.  It was very frustrating.  I was loading full size previews and using the GPU.  I tried various changes in the setup, turning off the GPU, increasing cache, and decreasing the preview size.  All had minor effects and I just had to alter my work flow to avoid LIghtroom.... until:

                                                                      I just completed another upgrade to my machine.  A new MSI G.L.G. 2011-3, x99a motherboard with an i7 6950x 10 core processor and 128megs of 3000hz DDR4. 

                                                                      I still have medium previews selected, now with 8gb of cache on an SSD.  I have the GPU selected and I'm using SLI on the two Nvidia 1070's. 

                                                                      So I have made a bunch of changes, and I can't be sure which are helping, but Lighroom is back to enjoyable to use as a great tool to process many photographs.  It's as if I turned back the clock to a 12 megapixel camera, HD video and HD screen resolution. 

                                                                       

                                                                      Still to say, that it does seem as if Lightroom needs a refresh to be 4k compatible at a lower cost to the user. 4k is here and the level of detail is such a great tool to grade and edit photo's and video it has become necessary.

You forced us all to go to CC and pay monthly and now the program is nothing like what we used to buy and run on our machines.

                                                                            There is nothing we are doing wrong with our computers or lightroom settings. I have read hundreds of threads by people with wildly different set ups and nothing works for any of them (or at best they get a marginal improvement that only works for a short time). You have ruined a good decent program with CC. Please do not act like you don't know it too. It is obvious from the responses that we all read from  adobe techs that you are clueless or hiding the real reasons as to why it is happening. Why don't you just tell everyone that you all use macbook pros because that is what adobe gives us to use and if don't use the same setups we are out of luck.

                                                                            One of the most advanced programs on the planet is not working and you are doing nothing.

If you read my last comment I am still upset with Adobe for lack of attention to working with this issue. They say they are working on the problem so let's see what happens. I do love the program.

                                                                                    Several things to make sure do and don't do.

                                                                                     

                                                                                    The number 1 thing you can do to speed up lightroom is use a separate internal ssd for the catalog and smart previews. I create a new catalog for each new event, and put that with my smart previews on an internal, separate SSD drive from operating system and raw files.

                                                                                     

                                                                                    After editing I import the catalog into a master catalog. This keeps my catalogs small and fast when initially editing.

                                                                                     

                                                                                    After importing files into lightroom and generating smart previews, I rename the raw file folder slightly forcing lightroom to use the smart previews (after smart previews are generated). Checking the check box for using smart previews in preferences isn't working. You can tell in develop mode when you look under histogram that it is still using the standard preview first. When I rename the raw file folder it forces smart preview usage. Before exporting I change the folder name back so lightroom uses the raw files for exporting and not the smart previews.

                                                                                     

                                                                                    There are lots of preference settings that people recommend and I suggest you research those too but the above is by far the best performance increase I have been able to consistently get.

                                                                                     

                                                                                    Another thing that will happen is when editing is that lightroom will begin to slow down the more changes to photos you make (especially brushes). Not sure what is causing this (maybe history steps?) but if you shut lightroom down and restart the performance returns. 

                                                                                     

                                                                                    Graphics processor can actually slow down lightroom unless you have a 4k monitor and fast graphics card.

                                                                                    • 39. Re: Lightroom CC is slow...

                                                                                      Lightroom CC has been running much slower for me since the last two major updates. I am planning to upgrade my machine and have landed on a mulititude of these discussions about Lightroom slowness and how it is worse with a faster machine. This is unsettling because I need a faster machine with more storage and RAM but am now concerned that I will have more problems with Lightroom. Hopefully Adobe will have fixed this problem by the time I upgrade. Every commment I have read talks about the problems occurring and becoming worse with a faster machine. I assumed it was because I have an older machine. The primary areas of slowness for me are using the adjustment brush and the heal/clone tools. It does not matter the order in which I use these tools, how many photos I have, size of catalog, etc. What does affect the increasing slowness is how long I'm in the program. Because of the age of my machine I have no other programs running while using Lightroom (taking a photo into Photoshop is a challenge). I have done some things that have helped alleviate the issues with the adjustment tool and healing/clone tool. The main problem with the adjustment brush is that the mask would not show no matter how long I brushed or erased (with visibility on). Often when lifting the brush away I would get a mask streak across the screen. My semi-solutions: For Masking: 1) Turn off auto mask. This makes a HUGE difference. Use Ctrl key when getting close to an edge. 2) Brush before using any adjustments or presets. 3)Turn off all pins. Also makes a big difference 4) Never use GPU acceleration--this is a useless tool and I believe the cause of most of the slow-down problems across all of Lightroom. For Healing/cloning: 1) Never have pins on. With pins off I can heal/clone endlessly and on top of others. However the more work the slower the changes occur, but I can keep on using the tool. 2) If I need to move the pin to a better source point, only turn on selected pin, move to new spot and turn off pins again. 3) If clone or heal continue to pick a bad source, switch from one to the other then back, i.e. healing source is bad, change to clone to get better pixels, turn back to heal. I call these semi-solutions because I shouldn't have to go through all of this to use Lightroom's tools. Also Lightroom eventually gets tired and I have to quit for the day. Other areas of slowness: stepping back in history, sliders not sensitive. I absolutely believe that the majority of Lightroom's slowness problems increased dramatically with the last 2 updates. The GPU acceleration is useless and any "animated" tool or button causes serious issues. It also seems that a faster computer should not worsen the problem. Faster computers don't seem to have problems with other Adobe programs that I'm aware of. I have seen hundreds of people leave for other programs, especially Capture One. This is a years long software issue that Adobe needs to fix. By the way, these issues are similar in Adobe Camera Raw and their adjustment pins, which are large and ridiculous, are so touchy it takes forever to hit the right one to make changes. If Adobe is going to update their programs, those updates have to be able to run on faster computers. I hope some of this info helps.
