I am running PFGW on three multi-core systems and am noticing some performance degradation using all cores.
I cannot figure out what is causing the degradation. Is it the memory, is it the stepping modes of the CPU or is there another reason.
For example: The tasks I am running on a C2D T5600 take 3600 seconds when one core is busy but it takes almost 5400 seconds when both cores are busy.
Did someone notice this as well?
