As a scaling factor scanning one message via spamc on a 2GHz Athlon with
1G of memory took 2.77 seconds elapsed time. Interestingly two at the
same time takes about the same time. Three spam scans, one on an incoming
message, seemed to take about 3 seconds. I'd conclude MY setup runs at
about 1 second per message. It'd chug heavily at a 50,000 messages a day
load without uniform density throughout that day. I use 40 of the SARE
rulesets and per user Bayes.
