tuning

[Martin Hepworth]

Hi

Well somethings obviously going very slow....

1. First thing to check is DNS. Have you got a local caching name server on
your machine.

2. In /etc/mail/spamassassin/*.pre what plugins are enabled?

3. Are you running ALL the RBLS in spamassassin. I find this really slows
down the system esp if 1. isn't enabled. Turn the ones off you don't want by
giving them a zero score in /etc/mail/spamassassin/mailscanner.cf.


Load average on its own doesn't mean much (just means x processes actually
waiting for CPU/disk/network), but if your hold queue is building then yes
it's a problem..
