How long does it usually take to scan a message with Message Sniffer and how does that compare with SpamAssassin?

Generally you can count the number of seconds it takes to scan a message with SpamAssassin on your fingers. Something on the order of 4-9 seconds per message. This method is NOT ADVISED with Message Sniffer as you would have to chop off all of your fingers save a tiny nub - about 220ms at most and often less than 1ms..
