  cpu 0 : socket 0, [core 0], hyperthread 0
  cpu 1 : socket 0, [core 0], hyperthread 1
  cpu 2 : socket 1, [core 0], hyperthread 0
cpu 3 : socket 1, [core 0], hyperthread 1
It's sensible to reserve cpu 0 for domain 0, and then put all your other
domains on CPUs 1 and 3 (leave CPU 2 empty, unless you know that you're
not going to thrash the chip's cache).

How can I know if I'm trashing the chip cache?
