I sometimes see "loading message" or "opening Inbox" delays against both 1.X and 2.X Dovecot servers from thunderbird. Is there some way to pin down whats causing them?

How long are the delays? There's not currently any easier way than straceing the process. Or could it be simply that the server is busy doing disk I/O?
