Re: [Dovecot] performance problem?

I'm running dovecot on a small server. I put all my mail from the last 10 years on it (approx. 160 mb).

I'm seeing terrible performance. Sometimes, my client needs several minutes to display a message. This is with mutt, thunderbird and evolution. Copying an outbound message to the Sent IMAP folder (15k messages) typically takes a few minutes, but can be quite fast on occasion (Thunderbird).

How can I debug this problem? I'm running dovecot .99.14 on a Mac Mini (OS X 10.3, 512 mb, 80 gb).

0.99.x's mbox code is pretty bad. Try 1.0-stables or 1.0-tests instead and set mbox_very_dirty_syncs=yes. That should make Dovecot pretty fast as long as you don't delete old messages.
