I'm suffering from a similar problem. I run a list with a few hundred
members that has a handful of posts an hour throughout most of the
day. About thirty people are on the digest list.
I'm running the Debian unstable mailman package 2.0.3-7 recompiled myself
on a stable (Debian 2.2) system. I contacted the maintainer of the package
and he suggested I post here. The machine is only a P133 with 96Mb of RAM
but I would hope it should handle such a list.
The mailing lists are running fine, mails just take a long time (several
hours) to pass through the system and it is putting an unreasonable load on
the machine in my opinion. It has a knock-on effect of making the web
interface unusable because the qrunner process perpetually has the list
locked (maybe this is a clue).
The python qrunner process seems to be running most of the time pushing my
load average above one constantly - it runs for its fifteen minutes and
then gives up. At some points during a lull of several hours in mailing
list activity it will stop of its own accord and everything will settle

If permissions were the case surely it wouldn't work at all? I've had a
look through and stuff generally seems to be owned by user list, group list
or owned by root, group list with g+rwX permissions.
I tried putting some extra logging in the qrunner script but wasn't really
sure what I was looking at. If someone can advise me where it would be best
to log then I am willing to hack the scripts a bit.
