Oh, we serve Maildir via Dovecot IMAP and 5000 messages per folder are a wimp. Problems start if the user:
We are having some performancec issues on our server at the moment - all I can put it down to is the large size of some maildirs. Eg.
ls -ld Maildir/cur
might show a directory >20Mb in size for some of our users (20-30k emails).
(Performance issues == everything is running ok then all of a sudden load avg goes through the roof, system cpu time goes crazy. Reading mail grinds to a halt. Then everything recovers just as suddenly and the load avg gradually returns to normal levels)
At first glance this sounds like a large folder is being indexed... are you using Dovecot deliver (which updates indices on deliver)?
With maildir, and especially dovecot, this problem effectively disappears! That's the theory anyway, right?
Theory is wonderful when it works :-)
In theory, Theory and Practice are the same. In practice, this isn't always the case. :)
