You've got plenty of CPU for mailman, I suspect... you're going to more
likely find your problems in the mail subsystem. I would STRONGLY recommend
dumping Sendmail as fast as possible. I use 'postfix' (http://www.postfix.org)
mostly because of its Author (who also wrote tcp_wrappers and SATAN),
and it is blindingly fast. I have 4 mailing lists that are 1K+ people
and I've never seen it generate even the slightest load on the machine.
You should also look at disk I/O as a throttle point... a single
drive is going to only be able to handle a certain number of IO transactions
in a period of time, and archiving especially can kill that. You might
want a seperate drive for your spool.
