[Mailman-Developers] Re: Huge qrunner process

[Barry A. Warsaw]

One ther thing to notice about qrunner.  It keeps a cache of MailList
objects referenced by name (see _listcache).  It does this to avoid
the overhead of having to reinstantiate the MailList object each time
it finds a message destined for a particular list.

You could try to redefine open_list() so that it doesn't cache the
objects.  I don't know how much that'll help, but it's worth a try.
