[Dovecot] Large Mailbox Slow
Doubt if there is any answer to this but will ask anyway. Have a few pop3 accounts with thousands of messages. Its slow when checking email naturally. Are there any tweaks to speed it up? I imagine there is an exchange of the message and header list which is the slow down. Too bad the list could not be compressed with gzip or something first. I think http has an option similar to that.
Just asking.

I am running Maildir format on CentOS 5.x 64bit with Ext3 on raid1. Often wander if Ext4 would have been better.
Only thing that comes to my mind is to use shorter uidl's to id each
email, not sure what method your using now.
I would seriously consider just changing it to use imap instead, then
you can be notified if there is a new email, instead of downloading
the list each time.

IMAP is a far better choice if you want to leave messages up on the server.
(XFS or ext4 plus using Maildir storage format on the server can also be a big help. But unless you have evidence that the disks are buried or the server's CPU is busy, those changes may not help at all. A good and quick tool on Linux servers to monitor that is "atop".)
