I just listed what I got and have tested. cpuminer runs a almost full copy on each core, so you should have between 70-120/Khs * 8. Just a guess, you're mileage may very. More cores more faster.

Thanks so your .zip file contains the optimized QRK based on those CFLAGS?

Nope, just the code. I can upload a binary, I'll have to compile it static.. pita and all. be a while....

I've included the libraries that ldd at least lists...? should run on most 64bit platforms.  cpuminer looks to expect it to be dynamic. Which is fine, but I'm not practiced at distributing binaries.
