For about two weeks, my Lightroom Classic has been painfully slow to open. Editing is slow. Navigating from image to image is slow. I have done no significant imports. I have three times optimized the catalog. I have plenty of disk space. The program is dead dog slow compared to only a month ago.

Has anyone else had similar behavior? Do you have any suggestions for me? I can only attribute it to a poor update from Adobe.

After trying a couple of things suggested in this thread (thank you to all who replied), my Lightroom was better but still quite ill. That was true up through this morning.

Then, I shut down my computer and Windows wanted to do an update. I let it. When I rebooted, I started up Lr looking at a...
not happening here.
 
Not happening to me. But a suggestion: turn off Sync with the cloud if you are not using it. And please check to see it is off ... do not say "I never use that feature", sometimes it gets turned on accidentally; you must check to make sure it is off.

I've never turned that on so would I do that. Might be good to know.
 
I've not noticed anything either. A few suggestions mentioned. Also resetting preferences can solve a lot of unusual issues. A re-install of LrC if that does not work. Personally I do a re-install first.

How full is your HD? LrC requires 20% free. Unofficial rule of thumb is 100GB.

Empty the cache. Delete the plist file.
Thanks. Editing and scrolling much faster. Still dreadfully slow to start up compared to a month ago.

I just got back from a trip and imported a few thousand images. It was crazy slow, burning up CPU, etc.

I let it settle in overnight and now back to normal. My guess is caching or previews being created.

One of the stated recent "new" features is faster culling, but I have not noticed that.

Thanks ZEEE,

I am seeing all sorts of odd behavior now; flashing screens, partial screen updates, unresponsive for long periods after mouse click. No other applications acting oddly. I've been using Lightroom since v2, way way back in the olden days, and have never seen anything like this.

I may reinstall. Any idea how many settings will I lose with a reinstall?

I have 575GB free on a 2Tb SSD.

"May reinstall", you say

There are other solutions in this thread you should try first, as they are less work and you can perform these solutions faster than re-installing.

Re-install is the last resort if nothing works.

I'm with you on that; reinstall is my last resort, but it's nice to have in my hip pocket if push comes to shove.

I continue to work on other suggestions. A few minutes ago I deleted my preview cache, Previews.lrdata. It was huge, but did not seem to affect performance in Lr. Still checking...

You don't lose anything with a re-install.I prefer that over reseting preferences and it does not take much effort. Nothing wrong with trying other things first.

There may be something here that may help. I follow this pretty closely expect for the using PS for multiple edits. Not an issue since the performance updates over the last several years.

Excellent link. There is a lot of good information there.
The only thing I don't follow in that link is using PS for multiple edits. Since the performance improvements over the last several years I've done up to 75 edits including multiple masks and no issues.
 
Did you make sure that Sync with the cloud is turned off?

In my opinion, resetting preferences fixes more problems than re-installing does.

Usually that is the first step. Often recommended at the Lightroom Queen’s site. It can solve all types of unusual problems. There was a recent thread there about someone having all types of issues and I recommended to reset preferences because that is the standard procedure followed by a re-install. The OP did a re-install first and it cleared it up. You never know.
