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?

Can you folks pin-point for certainty the specific version of Lightroom that starts exhibiting the same performance issue under the same machine setup? That would be helpful us to figure what happened. Here is a link where you can rollback to the earlier Lightroom versions https://helpx.adobe.com/lightroom/kb/lightroom-downloads.html.
@Dietmar You've provided additional detailed info in https://forums.adobe.com/thread/2210245. That is very helpful. Are the summary of your previous findings (copied as-is) still applies with the Lr 2015.7 and Camera Raw 9.7 release? Summary LR/Camera Raw has definitive a performance problem with some - especially my high-quality – PCs! I can reproduce the problem and I can demonstrate that the problem on other - especially my weak – PCs not persist or is not so strongly. With GPU on the proble...
What does Lightroom's Help>System Info... say? It should report the processor count and the maximum number of thread count used by the image processing pipeline? 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 ...
