OS related tweaks, probably not. However you could utilize a imap proxy such as up-imapproxy which if using FreeBSD is in ports.Visit: http://www.imapproxy.org/ to learn more. This should relieve the load on Dovecot.
We found that on our server, *not* using imapproxy improved our performance. We used to use imapproxy to great effect when we were using BincIMAP, but Dovecot is so darn fast (and caches its own authentication) that all imapproxy added was additional inter-process communication (translation: slower than just using Dovecot alone).
