[Dovecot] speed up dovecot IMAP server

[Bernics Gábor | Penta Unió Zrt.]

Hello, 

I upgraded my dovecot server (1.2 -> 2.1), from debian
backport because it was a little slow (wait 5-6 sec) when I opened some
mail (but not every mail).
Unfortunately, the mail open speed didn't
increase.
I think it's an index problem.
Have you idea for fixing?

(HP Microserver with 6 Gbyte
RAM - entry level server with small load and small (max. 40) concurrent
connection)

Best regards,
Gabor
