Spamassassin is slow - any tips or good commercial alternative?

My advice would be to run
MailScanner --debug --debug-sa
as that will print out all the progress of SpamAssassin, including a 
timestamp at the start of each line so you can see where the holdups are.
If you do that, and then show us where the holdups are, we may be able 
to help you some more...
