[QUOTE]Does 60ms sound good for 4 workers on 8 cores with 4.4GHz processor? [/QUOTE]I originally posted the response below to another, wrong, thread. I still don't know what might be hurting your performance. However, with a relatively new OS, driver problems immediately come to mind. Are you fully up to date with Windows Update and any main board drivers?

Misplaced response follows:
[QUOTE]If I understand correctly, you have arrived at the same setup which I have for my FX-8350. I treat each integer pair, with the associated FPU, as a "core". It has been a while since I set it up this way, and I may not still have the test results which got me here.

I think that I saw that a single integer unit, plus FPU, with the other integer unit not running P95, got better total results than running P95 with different LL assignments on the two integer units. Results were similar with LL on one integer "core" and P-1 on the other of the pair.

I now run 4 worker windows, with LL/DC assignments on the odd numbered cores, and the even numbered cores as helper threads. My rationale is that in this way each FPU, with the associated caches, are only doing one job, with two integer units, thus avoiding conflict over resources. Results were similar when I was running P-1 with the same allocation scheme, with the exception that Stage 2 only used ~1-2/3 'cores' once all the RAM was allocated.

I have been curious whether running 2 worker windows with 4 integer "cores" and 2 FPUs might perform any better through reducing memory contention, but some experiments made me think that this assignment scheme would not utilize the integer units fully. I don't know any way to see how hard a shared FPU is working. :smile:[/QUOTE]
