I built out a mailing list with 1800 members with bin/add_members, and it
was slow to add them. I later found out the drag was due mostly to all the
bounces that were coming back. (There were over two hundred dead addresses
in that set.)

Machine is a P3/550MHz with 512MB RAM, running NetBSD 1.5.1.

It's only been a few days, but I have seen no performance problems with
mailman delivery since. We're running postfix for the MTA. Cleaning out the
dead addresses was critical. We average about 100 messages a day.

My only real problem right now is trying to push 360MB worth of majordomo
archives through pipermail without crashing pipermail.
