I just turned CrayZ3 back on after a little tune-up, and it's folding a 6900 WU in 12:10 average TPF. This supposedly is 145k ppd according to HFM. The tune up was an improvement in RAM settings, and turning off NUMA. NUMA is a technology where one CPU on a multi-CPU system can use the RAM from other CPU banks. It slows down FAH because it FAH is not a "NUMA-aware" program.
