[QUOTE=daxmick;472719]Which, from the above results output, appears to be 20 cores and 6 workers, yes? (Which happens to be the suggested number of workers when I first started the program.) :smile:[/QUOTE]Nope. It looks to me as though 20 cores / 20 workers is better for you.

With apologies for jumping onto this thread. I just ran the test and got the following results for my i7 8700K, 6-cores. This indicates I should use the setting of 1 worker, yes? I have hyper-threading checked for trial factoring, but NOT for LL, P-1, ECM. For what it's worth, that's my default setting.

Yes

"With apologies....."
Please. No need. Your post seems completely agreeable with the topic. :smile:

Thank you both. Much appreciated.
