We have a few opt-in mailing lists that we are currently using mailman
for.  However, mailman goes to 100% CPU for a LONG time when we send
to our largest list (IIRC, it has ~15000 subscribers).  By LONG time,
I mean hours to days.

Does anyone here
1) have any easy performance-tuning recommendations?
2) have interest in taking a stab at tuning it for us?

I see there are some recommendations for tuning with Postfix here:

But I don't have a good feel for the likelyhood of these helping us.
