Cyrus-Postfix-PgSQL-Squirrelmail-WebCyrAdm and Spamass

[Patrick Nelson]

O/S -> FC3

I'm running a great setup that works great with 
Cyrus-Postfix-PgSQL-SquirrelMail-WebCyrAdm-Spamassassin.  Its on an 
older system (450MHz w/ 1GB RAM) with a SCSI HD dedicated to the mail 
store.  Everything works great and fast enough to handle the volume of 
my users (about 25), except for one thing...  Spamassassin!  I'm running 
it in spamd and spamc mode, but even so when a few email hit the system 
and goes through the filter (in master.cf) the system starts crawling.  
I watch this happen and it the CPU utilization goes to 99% when spamc is 
called (-> with mutiple email -> mutiple processes).  The good news is 
that even slowly, it continues to work.  The bad news is I'm afraid that 
there are probably timeouts happening.

I've searched for information on this and I had a hard time trying to 
find agreement on the exact cause and remedy.  Most people say the 512MB 
is needed, which I have doubled, and add an entery to the 
/etc/sysconfig/spamassassin command line options argument of 
"--max-conn-per-child=5".  I've done this and I can not really tell if 
things are getting better or not.  So...  What I'm wondering... Is:

Does anyone have any other things that I may try to get spamassassin to 
work a bit better?  TIA
