Not sure how much ZeroMQ is affected by this, but interesting to note
that these machines are becoming more popular.

"I had posted a message a few months ago about a 20uS delay I was
seeing on a new workstation.  I have finally figured out that it is do
to the fact that this is a NUMA system.  If I go into the BIOS and
change the setting to set the memory as interleaved, then the kernel
is not aware that is is a NUMA system and the delay goes away."
