Summary: bad performance for big queue dirs

Initial Comment:
Many filesystems (e.g. the popular ext2) have horrible
performance when there are many files in the same
directory.  The queue system should be modified to
avoid this situation.  As a test case, try adding
20,000 test address in such a way that Mailman will try
to send a welcome message to each of them.

Closing as won't fix for MM2.1.  If it's a valid problem
backed up by more experience and research, we'll address it
in subsequent releases.

I think you have a valid complaint, but I'm loathe to change
something so fundamental this late in the game.  I'll leave
this bug report open because if we can recommend some other,
more big queue friendly filesystem (reiserfs? I don't know)
then we should document this.

Don't MTAs have the same problem?  Do they all implement
multiple subdirectories for queued messages?
