Good post, but just to expand on it for the 2970wx, though the 2970wx was not tested, it is NUMA like the 2990wx and I wonder if it is likely to have the problem. That is unless the problem is in the number of cores and threads (24/48 for the 2970wx versus 32/64 for the 2990wx) and not the NUMA architecture. Anyone have any experience with the 2970wx?
