[Mailman-Users] Scaling Mailman

[Chris Greer]

We've been using Mailman for a while now, (still actually
running Version 1.1).
We've started to hit some problems with high message volumes to
individual list.  We are seeing multiple python processes trying
to deliver to the same mailing list, and getting hung waiting on
CPU.  

As we start loking into ways to solve this problem, I thought
I'd send a note out to see if other people are seeing this type
behavior and what they are doing to solve it.

Can Mailman be run on multiple receiving mail servers and safely
NFS mount the mailman directory ?   Or do we only get more CPU
capacity by going to a bigger box?

Have there been any performance enhancements between the current
version and the 1.1 version that we are running?  I've been trying
to find a Changelog, and haven't found what I'm looking for so far.

We are also using python 1.5.2.  I'm not sure what has changed 
in that distribution as well.  We are seeing some python processes
seem to have a fairly high memory footprint.

Right now we are running on Solaris, and for political and financial
reasons, that will probably not change in the next year or so.

We are also running our lists on the mail server with users.  We are
strongly considering moving the lists to a separate list server.

If anyone has any suggestions, I would appreciate them.

Thanks
Chris G.
