Re: Catching up Mail Groups

[gsstark@MIT.EDU (Greg Stark)]

I'm surprised at all this talk about expiration being slow; I'm using nnml
stored in that that lumbering behemoth filesystem, AFS.  And I read my mail
frequently throughout the day and get a fair amount of traffic, so it runs the
expiry process much more often than necessary and frequently deletes mail.

It takes only a few extra seconds between each group which seems reasonably
efficient. It looks like maybe some specific backend or option is triggering
some inefficient behaviour. 

I use gnus-total-exirable-newsgroups set to ^nnml:mail\.
and I use nnml as my backend.  I think dates are in the overview so
nnmh might be much less efficient.  The point movement in nnmbox/nnbabyl
should be fine, better even if it sorted the article-ids numerically instead
of alphabetically (as per my previous mail). Though it probably has to parse
date headers for all the newsgroups then run through them all a second time to
actually expire stuff, hmm that's sort of innefficient.
