LR works extremely slow

Hello to everyone! Recently I started to experience huge lagging in LR. To the point of impossibility to work with the application. Every move, every click ends in 5-10 seconds lagg. Often UI turns black, app "not responding". I tried to purge cache, add cache to 20Gb. Cache, LR and database is on the same SSD disk. Every disc have enough free space. Turned off GPU acceleration, reinstalled app, installed older version, tried to work without any data(photos), nothing helps. I never experienced any considerable laggs on my current or previous PCs. Any other software and games work perfectly.

P.S. I`m adding my PC info in txt file.

In general, I tried all the tips from the ones you listed. LR's performance is just awful. I think this is just a crappy code. C1 works absolutely fine, LR is simply impossible to use. However, thanks for the help!

I too have had problems with the latest version of Lightroom. Starting the program takes a very long time, so long that at time I have thought the click didn't register. Then I tried to start it again which ends up with errors about my catalog already being in use. When I finally see the program start it seems to go through a restart before any images are seem. Then the drive Lightroom is accessing shows 100% use. No editing can be done until the drive use returns to normal. AND, before anyone responds with a "Your drive is broken", I've already checked and it isn't. At first I thought the latest version had face recognition turned on again (Happened in a previous version update) but I can't find the menu that allows me to know if that is true. This is very concerning as I have no time for these delays. I have deadlines to meet and the product is slowing me down. The previous version did not have the delays I'm seeing here.

Pleasepost your own discussion. That works much better. This one was resolved. Many members might ignore resolved threads.

 

When yo do, include your system info as LrC reports it, example below.

 

Also, post a screenshot of your Library Module.

Does anyone know how far back I need to go to get resonable performance back?

I can't answer this question since LR is working fine on my both computers, without the bad performance you described. FYI; my desktop config is Ryzen 7 3700, 32 GB memory, OS on its own SSD, Catalog on its own SSD and photos on a HD. My second computer is a less powerful laptop with 16GB memory.

The poor performace you get is not normal. Obviously there is something wrong with your computer. Did you remove the LR cache as well the catalog and its associated folders from the scan of your antivirus? This can help a bit.

I was able to get the performance back by doing the following:

I checked all the standard performance improvements methods discussed in multiple posts and web site.  None of them worked.  Then I discovered Lightroom was working just fine on my older slower computer.  It shares the exact same catalog.  That made no sense so I started an exhaustive investigation on the difference between the two computers and Lightroom settings.  I could not find anything obvious.  Both computers are similar (the older one is much slower) and all the setting in Lightroom looked the same.  I decided to back up the setting from my older slower computer and copy them to my faster new computer.  However, before I did that I decided to completely uninstall Lightroom Classic and delete all the preferences.  Everything.  I then reinstall Lightroom with a clean installation and instead of coping the preference back from the old installation I just reconfigured Lightroom to the way it was before I uninstalled it.  And sure enough the performance I came to expect with Lightroom was back.  I have no idea why it slowed down so much but I am back in business.  Too bad it takes all that to get the performance you would expect.  Note that Lightroom only reciently started showing the poor performance

I agree with this assesment.  I also have a very fast computer designed specifically for photo processing.  Based on Passmark performance benchmarking my computer ranks in the 96 percentile worldwide.  The average computer has a rating of 3643.  My rating is 7745.  So I do not believe this is a computer performance issue.  I have tried many things to improve performance.  I even opened a very small catalog with no collections and it is still slow.  Many mouse clicks are delayed by several second.  I watched my computer performance while I was clicking and nothing came even close to maximum with any resources.  Lightroom Classic did not used to have these performance issues.  I am inclined to try an old version to see if I can get the performance back.  It is frustrating.  Does anyone know how far back I need to go to get resonable performance back?

I thought I was the only one having these issues till I got into the forum and read. 
The last two updates to LRC have been horrible and have done nothing but halt my work. 
So frustrated I even considered using the cloud base LR and it is so fast, but I like the classic.

Misty66.  Read my post on what I did to get the performance back.  Basically I uninstalled Lightroom and then deleted all the preferences files in User\username\AppData\Roaming\Adobe\Lightroom.  (back these files up first).  Then I reinstalled Lightroom and manually set the preferences back the way I had them.  Now Lightroom is back to normal performance.  I know it is a pain but it is the only think that worked for me.  None of the other recommendations worked.

So v 445.87 nice and current. Ok

 

When you updated, did you select Custom option, as to install a clean copy? Deletes all old ditrus left behind that might foul things up. Not normaly required, but often advised when having issues.

As for outside of Develop module, and some of this applies to Library and Develop

 

1. Face detection paused? It us a hog, turn it off (pause)

 

2. Next hog, Face Detection, pause

 

3. Any odd sync going on? see:

Also, Develop module only, location of Camera RAW CACHE, on a Windows rig, try to avoid placing it on the same drive as your OS Paging file, issue is compeetition of reaad/wrights on same drive at same time. Paging typically on C drive.

 

And Camera RAW CACHE can take advantage of drive speed as in SSD.

add cache to 20Gb. 

For issues in Develop module only, Consider bumping that up, say to 70

 

Note, this CACHE is supposed to purge upon closure.

Any other software and games work perfectly.

 

Meanigless, LRC does not behave as another program does. PS for one is a wimp in resource use in comparison, a spreedsheat? A word processor, wimps, A normal game? nope. A big huge heavily graphical game? Uses GPU a lot better.

 

Moving on.

 

Windows 10, and an NVIDIA GPU, and based on GPU model, I assume a desktop as opposed to Laptop, Some of the following can severaly stress a laptop. Oh, and may not work if the rig is one of thise All in One computers with the low power CPU.

 

Also note, following settings might get reset to defaults upon updates to OS or GPU driver.

 

1. Windows 10 power setting, see tip 8 in:

https://au.pcmag.com/windows-10-1/5180/11-tips-to-speed-up-windows-10

 

2. NVIDIA GPU, see:

That E drive, how much free space in %

 

Note, stated % very much on purpose, answering back with 1TB drive with 900GB filled is not %. Appears to be an issue lately with some members understanding of %. Yep, too long in home.

 

Drive with catalog needs to have at keast 25% free.

Disk C and E is one physical SDD (M.2 Samsung 970 EVO Plus 500 GB) disk. Disk E has about 30% free space (122 of 318Gb).
