Poor IMAP performance with large mailboxes

I wanted to migrate to M32 for IMAP support, but am finding *very* poor performance via IMAP. I'm running on dedicated a 2.8gHz P4 w/ 2gb ram & SATA HD's , so it's not a hardware limitation by any means.

I've got a large mailbox (~10,000 messages) that takes forever to access. I had to increase the TCPIP timeout from 30 secs to 10 mins to even do the initial population in Mozilla thunderbird. I also tried using squirrel mail web interface and again the script would timeout after 30 seconds and not populate messages.

I got my family migrated and then performance sucked so bad I went back to my old POP3 server until I can get it performing better. Is there some way to increase the performance of IMAP?
