[Dovecot] performance problem?

[Han-Wen Nienhuys]

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).
