P: 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?

Reading through the extensive discussion in the other thread, two other troubleshooting steps come to mind:

- 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:

start /affinity F cmd.exe /c "c:\Program Files\Adobe\Adobe Lightroom\lightroom.exe"

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.)

Anyone can confirm, that LR have performance problems with clone or brush tool on workstations with 6 or more cores?

Now version 2015.7, but I tested also with 2015.5, 2015.5.1, 2015.6, 2015.6.1. The problem ist version independent.
