Hi Ira,

ever since 9am sharp, my server has jumped to a load average of 5-6 and
is steady up there. I niced spamassassin but it's not much use, the LAMP
is still slow, which means the websites on the server are extremely
slow as it is. I stopped the Apache and MySQL and the load does not
drop. Spam has finally hit the big time I suppose.
If spamassassin was doing the perfect job done by Google, I'd shut up,
but it doesn't. it still leaves lots of false negatives in my box, and
what's worse is, it takes such a long time to scan each mail, that legal
ones fail and retry and end up arriving 2-3 times, or even 10. this is
becoming very unworkable. Unless I find a better solution, I'll have to
consider moving about 15 mail domains out to other hosts (And I am not
too keen about google apps)
I use spamd and clamav as daemons, triggered by simscan for qmail, and
the quad-core Xeon is sweating like a pig. if anyone has any ideas, I'd
love to hear them...
1. Run spamassassin --lint -D and check for problems.
2. Are you doing RBL checks within spamassassin? You shouldn't. Have
your MTA do the checks instead.
3. Are you using a cacheing nameserver?
4. See this link: http://wiki.apache.org/spamassassin/FasterPerformance
Best regards,
Henry
