Been playing around with new k version and noticed few things.
1.) k version ART dropped from previous version 59000 down to 1500 , thats a huge drop not sure what benefits it would give.
2.) k version SPM/HPM is lower on sandy-bridge than on j version using AV=1 (havnt tried all, but AV=1 always turned out fastest in previous version)
3.) k version using different m: values doesnt seem to make any difference at all.
4.) k version fluctuate between 90-100% usage on each thread all the time where the j version pegged to 99.9-100% all the time.
