Question

Lightroom Classic CC seems slower than previous Lightroom version it replaced

Lightroom Classic CC seems slower than previous Lightroom version it replaced.  To test the performance of the new classic update, I imported some raw pictures taken with a Nikon D810/D850 and am noticing that moving from one image to another (all with 1:1 previews) in the Develop module takes 4 seconds before the image is displayed after pressing an arrow key to move (or using the mouse to select an image).  When you move to another image, the UI is repainted first (and, i assume, the histogram calculated, etc.), and then the image is displayed on the screen.  Moving between the Library and Develop modules also results in about a 4 second delay before the image is displayed.  Moving between pictures in the Library module is almost instantaneous. 

This level of performance is unacceptable.  Doing a copy/paste of settings from one image to another takes longer in the latest Lightroom than in the previous one as the time needed to display the image seems to slow everything down, thus slowing down the entire workflow process.

Another quick test was to press the right arrow key 10 times in succession in the Develop module to move between images.  It took Lightroom Classic CC 20 seconds before the UI finally caught up and displayed the desired image.  Doing the same in the Library module takes about 3 seconds.

Or, is this just the level of performance to be expected?  Was this not tested during the beta process, or just deemed satisfactory by Adobe? 

What's the best way to get feedback directly to Adobe on this?

    Still no luck with 7.1 performance is still abysmal. Its pretty clear that a lot of Lightroom users are having this issue as well. Starting to doubt that these performance issues will actually get fixed.

    Anybody that thinks Adobe will address this is delusional. They have a long history of ignoring problems, and it’s cklear they will do as little as possible for us dinosaurs that still don’t use a phone for their photography. Lightroom CC is the future, Classic will receive camera and lens updates while all the cool new features go into the mobile product. You watch just like Apple abandoned Aperture for the mobile platform, Adobe will kill off Classic entirely within 5 years max.

    7.1 made no difference, I barely have any presets, have tried everything trick and it still slows to a crawl after about 10-15 minutes. I have become very proficient in DxO Photolab and C1 Pro 11, just use the Library module of LR mostly or quick RAW processing occasionally, so I’m no longer as annoyed, at least other companies still care about photographers.

    Well I'm on the new 7.1 version and nothing has changed, switching between photos (d810 raws) takes up to 3-8 seconds, this way it's impossible to check and select photos from 600-900 photos that I import at a time.

    This is my workstation setup, I highly doubt that this would be the problem...

    4k monitor, using it in 3200x1800 resolution (plus a 1080p monitor on the side)

    i7 4790k

    32GB ram

    nvidia 1060

    double intel ssd's in raid0 for operating system and lightroom

    four 15K Cheetah SAS drives in raid 0 for data storage (where I store my raw files)

    (camera raw is set to 100GB and all those "nice" features like face recognition and mobile sync are turned off)

    What could I do? Jobs can take up to 2 or 3 times more hours to finish just because lightroom is becoming unusable

    How many presets do you have? Lightroom slows down tremendously when switching between images in develop when you have a lot of presets.

    Also note the type of presets. I have seen cases of VCSO presets causing serious slowdowns.

    Import/Preview generate goes lightning fast for me.

    The CPU goes up to 90%+ (Ryzen 7 1700X - 8 core 3.9GHz, GPU is 1060, 16GB RAM , SSD 850 EVO).

    I create 1:1 and Smart previews at import, but no conversion to DNG.

    Older LR only used around  15-20% of CPU when importing/exporting.

    Just check 'Generate previews in parallel' in preferences > performance tab.

    Develop module is another story...just unusable for any serious work.

    It kinda beats the whole purpose of using lightroom for its fast workflow.

    10 brushes + 10 healing spot pretty much kills it...zoom to 1:1 takes  3-4 seconds, pan is sluggish, changing between photos takes 4-7 seconds.

    I have just discovered that changing Process to version 3 (2012) restores some of the develop module performance.

    Another weird thing: exporting 4 files makes LR jump from 6 GB memory usage to 9 GB!

    Once the export is over it keeps 7 GB memory usage.

    After two days of use, it improved definitely compared to 7.0, still in develop module it is sometimes quite slow and a few seconds delay may well happen. In these cases, everything in the UI updates slowly (menus, panels) and at the very end the image. Should be the other way round. Also, after switching images in "d" mode using film strip keyboard shortcuts such as switching on/off image text sometimes is sometimes not possible for a few seconds. So, back to normal poor known 6.X performance but not improved as promised.

    Adobe LIED to us! Speed issues in Lightroom Classic CC - YouTube

    It is not a 5K issue. Why does Adobe now release new features in CC instead of fixing performance issues ? Do they still listen ?? I have not seen any official response yet accepting that users have severe performance issues and promising that they will fix ist.

    I agree! Adobe needs to listen to what we are saying and address this now before people start switching to alternatives.

    Try the new v. 7.1. Mine is much better and faster now.

    I've just spent some time on chat with Adobe Support.

    Adobe is aware of LR Classic performence problem on 5K displays. I really hope fix will arrive ASAP! This is real pain.

    I have a six core processor @ 3.5ghz, 64gb of ram, 4 raid 0 ssd's, and nvidia 1080. I have set aside 100gb of camera raw cache, done all the recommended steps to improve performance (generating previews, increasing cache size, optimizing uncatalogued, etc...) but still LR Classic Slows to a halt after 20min of work. Not sure what more I can do at this point to make LR more responsive.

    Adobe, I thought LR Classic was supposed to be faster!

    Maybe my performance has appeared to be good because all of my testing has been short term. Having just gotten back from a trip to Virginia I have a bunch of edits to do so I'll exceed the 20 minutes in working on these. A question - when you run into the slowdown, does shutting down LR and restarting give you another 20 minutes before it halts?

    When I restart lightroom the performance is great. However after 20min or so it slows to a halt.

    Hi,

    just one nice example of how really slow is my LR Classic CC on iMac 5k - i5, 16GB, 512BG NVMe SSD.

    https://www.youtube.com/watch?v=xHJlAMrlKks

    On 5K display - scrolling 0-5FPS and on Cinema Display (nonRetina) - +25FPS.

    My guess is that LR cannot handle super high resolutions screens.

    And also there is no GPU load show in my iStats while scrolling or exporting in LR. So what exactly is GPU powered in LR, Adobe??!

    Really tired of this!

    Hi janmalycz

    I haven't been entering this conversation because I thought it was mostly about response in the Development panel, which I'm currently not currently using. But I see you are scrolling in Grid view. All I can say is that I have a similar setup, a little more high-end on the computational hardware (iMac 5K with 4 GHz Core i7 & 32 GB of RAM & 2 GB of video RAM), but with a Fusion drive and catalog and photos on an external 4-disk RAID 5 (which might be slower than your setup). I have my main screen in high resolution (3200 x 1800 pixels), which tends to slow down Lightroom and have a 2° Cinema display. I have done nothing to optimize Lightroom (e.g., I am not maintaining full resolution previews).

    My sense is that scrolling on my machine is 4-5x faster than on yours. I get a lot of "greeking" (pixelation) when I scroll, but upon stopping scrolling, the Grid images update in about 1 second. I know that this doesn't identify the source of the difference between our machines, but I think that you should be able to speed yours up, somehow.

    still not usable for me. 350% CPU load, incredibly slow develop module. Letting LR stay open over night (was always possible before upgrading) lets LR become so slow that even menu scrolling is impossibly slow. Bad SW. Promoted as performance upgrade. Incredible. You can work at max 30 min before you have to restart to get a bad, but almost usable SW. It gets slower and slower. CPU load incredible. Switching on image text takes many many seconds, switching images in dev. module takes longer and longer.

    Working in iMac late 2013, 3.2GHz, 24 Gig RAM, i5. GeForce GT 755M. No Antivirus SW.

    The problems are now known since weeks. Where are the fixes, Adobe ???

    Lightroom is slow so that I have to stop using it. It is painful and frustrating to try and do anything since the last update. What can you use an alternative to lightroom???

    I was having a lot of trouble with Lightroom running very slow "Not Responding". After reading a post in this thread about excluding the Catalog and Raw files from the Antivirus, I remembered I had recently installed a new AV (Bit Defender Free) instead of using Windows Defender. I un-installed it and went back to the included AV in Windows. That solved the problem, Lightroom is running at a decent speed.
