Lightroom: Slow performance on Xeon CPUs
I noticed that LR clone and brush tool on my XEON E5-1650 0 3.20GHz (Attention: E5-1650 0 and not E5-1650 v4) can not stress my CPU and after x minutes of working LR slow down, until I have to restart it.
Please see the full diskussion with the problem here: https://forums.adobe.com/thread/2210245 (test with different Lightroom versions, confrontation with a weak laptop, that works fine, tests wit other graphic grafic card, test with other bios settings etc. No results. Only restart LR or minor display resolution helps.)
Can anyone with an XEON E5-1650 0 3.2Ghz confirm this?

Some made the observation that Lr was performant right after a launch and then gets slower after intense brushing. Is it on a single photo or do you typically have to walk several photos to reproduce it? Do you remember which version of Lr this started to happen? Do you have Lr mobile sync turned on? What happens if you pause the sync and then relaunch Lr?

Here is a link where you can rollback to the earlier Lightroom versions https://helpx.adobe.com/lightroom/kb/lightroom-downloads.html.

- Does LR's memory usage as reported in Task Manager increase dramatically as it slows down? That's a typical symptom of a memory leak.
- Try restricting LR to running on 1, 2, 3, or 4 processors. Open a command prompt and paste this line:
An affinity mask of "F" specifies 4 processors; use "7" for 3 processors, "3" for 2 processors, and "1" for 1 processor. (The mask is a bit mask specified in hex.)

I think that this excludes memory problems.

Can we have a comment from Adobe on this please. Can't you replicate it?

Point 11: When I reduce the resolution of my the display to 1280x1024 that helps a lot. Then slow down only after more time...
I would say that the problem "slow down" has to do with not only with cpu, but also with display resolution ( but not with graphic cards or driver because I tested with different graphic cards).
P.S. Is here anyone from Adobe? I wonder if it makes sense post experiences, or it is lost time? A statement: We know the problem and working on it, would help;-)

I'm using LR on an i7 6 core machine and after upgrading to a 4k display I'm experiencing similar massive performance problems.
