Hi,

we run a list with 35.000 users on it. We run it on a Debian Slink
server. While Mailman "prepares" the mails top shows a python
process suck up 90-95% CPU for a little while. Then it drops drastically
and the mta takes over (exim). Our server is also our web server and
http connect speeds does not seem to be affected by Mailman.

But I have to say that Mailman has dealt very nicely with this
relatively large list. I can not tell if the hd is grinding though since
the server is located outside of our offices.
