If you want to investigate the NUMA topology of the system, which we
refer to as "locality groups", you might start with the following
commands:
https://illumos.org/man/1/lgrpinfo
https://illumos.org/man/1/plgrp
These manual pages link to other related topics, including a library
for locality group awareness in an application.
I really wouldn't leap straight for "it's a NUMA problem", though.
