And of course you can cluster MS quite nicely anyway.

I put a little how-to get best out of SA on the wiki a few years ago, some
of which is still relavent (local caching DNS etc)..


and the previous section on that page is also useful..


Depends how many messages you need to run, but you can crop alot at the
incoming MTA byt things like delay helo, recipient checks, greylisting and
the like. I've seen people drop well over 80% of spam that way well before
it hits your actual spam checks.
