What's your swap utilization?  1gig of ram using tempfs and MailScanner
sounds like too little ram...

I've been wanting to use Bayes for our mailscanner system, but I'm
wondering now if the overhead is worth it.  We have a new mailscanner
box running with Postfix (under Gentoo Linux) and it works pretty
we're filtering between 75-80% of our mail as spam.  The box however,
hammered, it's running around 5-6 with spikes to 8-9.  I've just
off bayes and I'll see how the load is once it's processed all the
logged messages.  We're averaging about 15,000-20,000 messages a day
(probably more once the school year starts).  Mailscanner is running
an HP DL320, hyper-threaded proc, 1 GB of RAM, and raid 1 drives.

Is that normal for using bayes with mailscanner or do I need to tweak
some things?

(I'm already using tmpfs for a little bit of a speed up).
