I'm probably stating the obvious here, but a ZEO server + at least one
ZEO client is generally advisable at the very least for debugging
purposes, in which case dual CPUs/cores can be somewhat helpful
(though the zeo server is not terribly processor intesive in my
experience).  Even with a non-ZEO setup, dual cores could obviously be
helpful if you were running other cpu intensive processes like an
RDBMS on the same system.
