server sizing question

[Jeff]

Hi all,

Does anyone have links to recommended server sizing for cyrus.

I am migrating away from sendmail/cucipop to postfix/cyrus.  I currently
have about 7500 mail boxes with about 16GB of mail.  The majority of my
clients will be popping mail, but we are planning on supporting IMAP now
that we have good quota support.  Each client will be limited to 20MB of
storage space.

How does cyrus compare to cucipop in handling the load.   

Thanks,
Jeff
