doh, meant to send this to the list instead of just to russ :)
disclaimer: some of what i'm talking about may be slightly off.
if i'm not mistaken, the point of the big-todo patch is to keep the
individual queue directories from containing a huge amount of files. the
default qmail install uses 23 directories, and if you have (say) 25000
messages queued up, each directory will probably have over 1000 files in it.
the problem with that is that there are some filesystems that get VERY slow
on readdir() calls with lots of files in the directory. i think this is a
well known problem with ext2fs on linux, i know i've seen it happen before
when i had 20000 postmaster messages in my maildir one morning. using
big-todo can alleviate this problem by reducing the number of files in each
queue directory to something that readdir() can cope with better.
however, it's probably only useful for a site that does a LOT of small
messages, each with different senders and recipients. if you're just
running a list server or something i doubt it will make much difference.
still, i doubt it will hurt anything in any case, but someone else might
want to comment on that.
