[Dovecot] performance problem?
Hi,
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).

mbox or maildir?
I'm using an Am486DX4-100 with 64 MB to serve my personal mail. (about 650 MB distributed over about 100 imap folders)
The performance is quite ok although obviously it's not blazingly fast.
Greetings,
Gunter

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.

Thanks for your consideration. However, I'm running maildir, and I think something's fishy with MacOS's directory handling. Haven't figured out what, though.
