That is the Info + Tool that I was looking for, thank you both onedeveloper and coinbutter.
I don't know if affinity is usefull on Intel cpu's, but works just fine for amd modules with shared L3 2MB cache.
going back to testing.
I'm surprised it's needed on AMD with modular cache. Modular cache only causes a hit if the thread moves to a core supported
by a different cache module. Miner threads should always stay on the same core.
Can you do some testing to find if you can get better performance with a custom affinity?
