Increase Performance howto

[Dhanny Kosasih <dh...@gmail.com>]

I tested my qmail wtih more than 14000 spam (i used qmail-inject in my 
script). If i use QSheff + ClamAV + SpamAssassin, my server process 
14000 emails in 1 hour, and if i only use qmail my server process 14000 
emails in 1/3 hours. How can i increase my server performance ? I don't 
understand what 'max-connection' and '-m' for, can u tell me what is that ?

Regards,
dankos.

If you do not already have a large amount of memory then adding
memory is one of the sovereign cures for slow SpamAssassin. As soon
as it goes to swap you're dead.

More processor also helps.

Fewer rule sets leads to poorer filtering and faster operation.

You are already processing much faster than my 1GHz Athlon which has
a gigabyte of ram. With all the rules I run it takes on the order of
a second and a half to scan for single messages. With multiple messages
at once there is some net advantage to the multiprocessing that happens.

It may be time to split the server into two machines.
