Hi All,

What are the tips/tricks to make the QT run any faster than what it is currently?

What areas can be checked? Like where the performance bottle necks are?

Also, how can we have virus scanner and spam assassin run on a separate box to that of the core mail server? If it would help in a performance boost? How can such an installation be done?

Thanks for your help.

QMT is about as streamlined as can be expected. You could so some things like limit the number of spam checks it does (or disable altogether), stop it from scanning for viruses, etc. Might shave a couple tenths of a second off of messages.
The rest of what you're asking *COULD* improve performance (only if over 50,000 email accounts, and more than 100,000 messages a day incoming), but would require a cluster setup. You'd need at least 3 machine, setup NFS for your /home and /var directories and share the MySQL DB. Then machines could be set to specific tasks, but this wouldn't be of much benefit unless you're running an ISP.
In my experience, a good P4 CPU (not a Celeron...), and a Gig of RAM can handle just about anything you throw at it. Other services running on the same machine could slow it down a little, but I run Apache and ProFTPd on my machines (with 1G of FTP traffic daily) without any noticeable bumps. The only time I've really noticed a lag was when running rsync to backup the web/FTP directories to a remote machine from a cron script. I would open about 20 rsync threads, which ate the entire bandwidth on a fractional T1.
