FYI, there's a mining patch from @penguins (penguin on golos) via @picokernel that improves mining performance. Unpatched PCs are only running with one effective core, no matter how many threads are configured.
@contentjunkie has distributed a compiled binary for windows, but for some reason that version doesn't seem to be working properly in my environment. I tried on 3 different PCs and can only get it to use 1 actual core, no matter how many threads I set in config.ini.
I saw that yesterday and compiled a binary with it. I did not see any hashing power improvement but it found a block for me just half hour ago.
I did not post on Github yet.
