high cpu load and recommend max-children value

[Rejaine Monteiro]

Hi

I'm runing spamassasin in a mail server P4 CPU 2.80GHz HT - 2G RAM - 2G Swap
I'm using qmail  + qmail-scanner 2.01 + spamassassin 3.0.4 + clamav
My spamassassin contains: razor2 , dcc,  fuzzy_ocr, rlb_checks,  
bayes=yes, autolearn=no, autowhitelist=no  (with options "-x -u spamd -d 
-m 5")

Qmail-scanner statistics :

Average 123 Msgs / 5 min
Average 5 Viruses/5min
Average 95 Spams/5min

But we have some problems with high cpu load and spamd ( cpu load ~ 7, 
8,  9)

What I'm doing wrong?
