I guess you don't have anything CPU intensive running.
General good practice for sysadmins is to affine CPU cores/threads so that you don't end up flushing the CPU cache too aggressively and you don't split your VM's over NUMA zones because memory locality is important.
Well, I was asking what the actual result was. GP (who didn't respond to me) mentioned it was an experiment.
TheDong gave experimental results in a reply though.
