I would love to see the results of that, including more information
about the architecture in question.

Indeed. I'm currently trying to convince Netflix that the way
to get the
most performance out of a NUMA machine is to boot a different kernel on
each NUMA domain. One way we might demo that is on a 4 domain system
lock down 3 hypervisors and their guest OS to 3/4 of the NUMA domains
and give the host kernel the 4th.
