So if yespower is memory bond than cpu speed, how i can configure the memory in Linux to work best for cpuminer-opt v25.1? Is hugepages setting has any effects for cpuminer-opt? Or that it just need ram with recent speed or l1,l2,l3 of processor size?
There's no real short answer for this, pretty much all of the above. You can enable transparent huge pages on Linux and give it a try.
If hugetlbfs is enabled verthash and scryptn2 will try to use them.
Edit: a little clarification: I/O bound doesn't mean it uses a large amount of memory, it means it accesses memory a lot. Huge pages won't help with that.
