Hi folks I seem to recall, though I can't remember where, seeing about 6-8 months ago, reports of some strange network jitter for these platforms. This is Nehalem/Westmere specific, didn't impact the earlier CPUs. For some reason, my memory is of a strange driver-NUMA connection, but I am not sure at this time.
Trying to trace something down, and gathering the background material first. Gigabit ethernet, Intel NICs on the motherboard. Single IOH. Thanks!
