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!

Wild guess, but it sounds like your virus checker is scanning the catalog file or the Lightroom executable (or both), and it shouldn't be doing those scans.

I moved Lr and database to whitelist and turned off Bitdefender. Problem is the same.

I have had the same problems but mostly when I work in the Book Module and are going between it and the Develop Module.  I did everything you did and followed all of the steps recommended by Adobe but no luck.  The only thing that seems to work is getting out of LR Classic and turning the PC off.  Then when I reboot it is as if nothing happened.  I have asked the Community but nobody has come up with anything that I have not already done.

Your attachment fails to load, or that is not an attachment.

 

Please post your System Info as Lightroom Claiic reports it. Please include all info from first line down to and including plugins.

 

Oh, and please, not as an attachment. Attachments often fail on this site.

/EDIT/ahh, you stated "I moved Lr and database to whitelist and turned off Bitdefender. Problem is the same."

 

So BitDefender, possibly need to add an exemption fir Lightroom Classic catalog files.
