What's the average processing time for a message, and are you using any
-i flags on your spamass-milter commandline? Grep your maillog for
"in .* seconds," to get the timings. If they're all under 10 seconds
or so and you're not using -i, check for things like mail loops, or
large outgoing mail bursts.
