Argh, I'm sorry. I meant yespowerR16 instead of yescryptR16 in my last item! And I was referring to bellflower2015's fork of your miner (you can easily find it on github).
Thanks!
I suggest you not set the process affinity explicitly, it confuses cpuminer. Also please add -D option
and post output.
About yespower, I see the correction you made to your initial post. If I understand, you observed a drop
in yescrypt performance over v3.8.8, but the big difference was with yespower vs bellflower fork.
I can't explain the yescrypt difference, as I said I made no changes but I'll take another look.
I'll also check out Bellflower.
