[Mailman-Users] how much can one mailman support?

[Dave Rasmussen]

Just how many lists can you run on one mailman server on a uniprocessor
dell server running linux and have enough left over so when users request
to know which lists they're on, your box doesn't come to a grinding halt?

We're considering putting 6000 course/section lists on it plus migrating
another similar number of existing lists that used to be sendmail include
style reflectors (prone to spam).

I suspect it may be able to handle the lists, but as soon as users request
to know which lists they're on, are they going to bury the server?
