BTW, although I know next to nothing about NUMA, I do know that it is
configurable to some extent (eg, via numactl). What was the
configuration here exactly, and did you try alternatives? Also,
what was the OS exactly? (I've heard that RHEL4 is a whole lot better
than RHEL3 in managing NUMA, for example. This may be generic to 2.6 vs
2.4 Linux kernels, or maybe Red Hat did some extra hacking.)
