We are receiving near this much mail traffic, I get about 1 connection every
2 seconds, average of 50k messages per day.

I am using spamD on 3 different servers to spread the load around, it's
working great!

In am also running my own creation (WinSpamC) which allows for
load-balancing between multiple spamD servers, without this, things might
not be so pretty for us!

Try turning off Bayes and see if that helps increase the scan time, I've
seen a few issues with corrupted bayes!

Are you using the -m switch with SpamD??  Try setting this to a value of 10
or 20 and see if that helps.
