Persistent IMAP server connections is a different story. In some situations that could help. But it's also not trivial to set up. You could look at using an imap proxy to emulate persistent connections. I believe Timo (dovecot's author) once showed that dovecot is faster than using a proxy, so don't even bother with a proxy when using dovecot.

For our installation, using up-imapproxy with Dovecot did improve performance. So, YMMV, and I recommend actually testing to see how things work either way.

(We do a number of things that may make initial login more latent than it may be for other people using Dovecot and that probably accounts for the difference.)
