I have a (bit aged) Redhat 9 box (Pentium II/512Mb RAM) running Mailman 2.1.6 with Postfix. Its only has to run a single moderated mailing list sending out one email every day to around 20,000 subscribers.
Sending out the emails is not problem - it works great. The major problem is logging in to approve the email. It (Apache/2.0.40) is so slow that it usually times out with a 500 error after you try and login.
Is there a way of speeding up the web interface?
The web admin interface itself? No. You may be able to speed things up indirectly, by breaking up the list into multiple sub-lists and having an "umbrella" list that goes by the same name as the current single list.
The issue is that each list configuration is stored in a single Python "pickle", including the complete list of all subscribers, etc.... Breaking this up into multiple Python pickles is likely to help reduce contention, and speed up the overall performance.
Can I approve postings from the command line?
Most large mailing list sites that I know of work pretty much exclusively from the command-line. However, you'd need to search the archives for more details on how they do that.
There is a large archive as they have been running this for around 3 years. Will it speed up if we trash part of the archive. If so how can I trash archived data that is (say) over a year old?
I don't think the size of your archive is going to have any impact on this issue.
Most of the "performance" related stuff in the FAQ is going to be with regards to getting mail out to the members as quickly as possible, as opposed to the speed of the web admin interface. But you may find some stuff there that is useful to you.
