The answer to your question depends a great deal upon the server that you
are using.

If you are using UW imapd with the default traditional UNIX mailbox
format, it is no surprise that you have performance problems with 1GB
mailboxes.

The easiest upgrade is to change the mailbox format in UW imapd. If you
want to stay with flat files, mbx format works much better (but don't use
NFS with it) than traditional UNIX format but still once you get into 1GB
territory you're pushing the boundary. The newest preferred mailbox
format in UW imapd is mix, introduced in imap-2006, which splits into
multiple files and uses an index.

Feel free to contact me by email if you have further questions.
