So why would it take so long to display the list of all mailman lists that we run? We have about 450 lists and it takes just over _1 minute_ for the list of lists to display. Meanwhile, access to individual list pages takes only 1 second - so it's not a slow server. Is there any way to speed up this time? Thanks!

Mailman doesn't cache that data, because on a big server, the description or the visibility can change at any time. Therefore, when you request the main list page, it has to go into every list's config.db file and check the description and the visibility to make an up-to-date list. This obviously takes a while. I think 1.1 sped it up a bit, but it still definitely takes a while. Individual lists take much less time because there's only one file to open.

O.K. I trussed the process and noticed that it stats _every single_ config file before opening _each_ one so for 450 lists that's 450 * 450 = 202,500 stat calls! It's no wonder it takes a minute.
