It takes an hour >to load on 1.8 Opteron. 2 remarks: (1) You mentioned /GL -- that is link-time code genration, not POGO. Did you really compiled with POGO, e.g. built instrumented version, trained it, and then built optimized one? (2) Output that you provided says "System is SMP, not NUMA". When I start Carfty of Windows Server on AMD64 it correctly recognizes it as NUMA. I am not sure who is guilty here -- Windows XP or BIOS settings. If later than there should be a way to turn NUMA support on. Thanks, Eugene
