dovecot - Jan 2013 - speed up dovecot IMAP server

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?

My
conf:

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

Best regards,
Gabor

You have provided insufficient detail to troubleshoot a performance
problem of this nature.  Do note the latency could very well be an issue
with Kmail and not Dovecot.

Did you performed any troubleshooting, any investigation, of your own,
before upgrading to 2.1.7?
