Depending on how/where sa is called from (remote/local/MTA) may give you some options, or limit you in some others.Hello, all.
I have operated some mail dedicated server using redhat 9.0. About over 4,000 users use this mail server with pop3. But it is so slow and some spamd seems that spamd can't process well.
So I raise the number of children spawn like below.
SPAMDOPTIONS="-d -c -m9 ==> SPAMDOPTIONS="-d -c -m10 Is it a good method to increase the number to solve the problem? Or any other good method?
Surely I have read this article. http://wiki.apache.org/spamassassin/FasterPerformance
# echo $LANG en_US.iso885915
H/W : Pentium III 1G Dual, 2G RAM, OS : Redhat 9.0/ 7.3 / kernel 2.6.11, pamAssassin 3.0.2
Thanks in advance.

What I would do if I had the budget (this is my opinion) is to add another box, then use round-robin to have the MTA send work to the other server(s). This way, you can distribute the load a bit better with out raising the children etc. But this only would work in my case. I currently use the MySQL bayes/awl/user_pref databases. This would scale nicely by adding another box with my setup. Another option, if network lookups are killing you, is running a local mirror for urirbl/rbl lookups. I don't currently have local mirrors, but my mail load isn't nearly as high has yours. I've found, in my experience, that sa scales better across multiple boxes with a few number of children, than one gigantic server with many children. Again, this is my own experience, and I can't attest to any others.
