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?

If you are an existing Lr Classic CC customer, and would like to test out a developer preview build that we think fixes this performance issue. Please send me a note and I'll make sure that you are invited to the prerelease program. Thanks.

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
  1. LR/Camera Raw has definitive a performance problem with some - especially my high-quality – PCs!

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 an...

I get an error when I login to it - I think it is probably because the pre-release invitation went to a different e-mail than my registered one I use for Creative Cloud.

rrr007@earthlink.net is the correct e-mail... sorry for any confusion!

I have the same issue as Reed Radcliffe but didn't want to post my main email address here because of spam issues.

I observe the same (slowdown of LRwith more editing) problem on i7/4 core MacBook. All adjustments are basic (no healing brushes or selective adjustments).
