I have a test box with the same specs but 8 Gigs of RAM. My performance
tuning so far has been

- tmpfs for message scanning
- DNS caching server on the same box
- Lower timeouts on Postfix (another instance handling retries)
- Compiled rules on SA
- DCC, Razor
- Clamd
- Asyncrhonous logging

Filesystem underneath is XFS and average mailsize is around 60KB. I have
pretty much made all the changes suggested and currently the server is
handling around 45000 emails/hour. Do you think increasing the number of
MailScanner children might help? What other performance tweaks can I have? I
am looking to scale the system to handle at least 65 emails/second with
antivirus, antispam scanning and RBL checks.
