nice.<br>
<br>
depends on the tests you run (RBLs etc) and the size of the emails.<br>
<br>
look in the wiki for performance and tuning on both MailScanner and<br>
Spamassassin.</blockquote><div><br>
<br>
I have a test box with the same specs but 8 Gigs of RAM. My performance tuning so far has been<br>
<br>
- tmpfs for message scanning<br>
- DNS caching server on the same box<br>
- Lower timeouts on Postfix (another instance handling retries)<br>
- Compiled rules on SA<br>
- DCC, Razor<br>
- Clamd<br>
- Asyncrhonous logging<br>
<br>
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.<br>
