If it is a single folding slot using all available threads, it's definitely not good ... limit the slot thread number to the number of performance threads.

I spent a little time with it. When set to -1, the cpu:30. I experimented with setting the cpu to 8, 16 and 20 and didn't see any real difference in performance. Project 16969.

That sounds either problematic or disappointing.

My ~8-year-old e5-2690v0 @ 2.9GHz (turbo boost OFF, DL380g8) running CPU:30 gets ~270k PPD on p16969.

FWIW I have found that v0 (32nm) cpus far outperform v1 and v2 (22nm) cpus for F@H. I have only worked with the Xeons of this generation, not the consumer level chips.

You should see most performance when limiting the number of threads to fit your P-cores only. As FaH overall performance is capped by the performance of your slowest CPU core, you don't want to share work between P-cores and E-cores.

Things are complicated by Windows 11 dumb scheduler which doesn't understand complications like this, which might get into its head to put work on E-cores if you run FaH on more than 8 threads. Try setting 16 threads (assuming no GPU folding!) and disable E-cores altogether and see what happens... :) Because of the limited smarts of the scheduler, I'm not sure how effective it will be to create two FaH CPU cores, one with 16 threads for your P-cores and one with however many threads you want to dedicate on the E-cores. Who knows where each thread will end up, as Windows tends to throw threads around all over the CPU for no seemingly good reason.
