How much ram? our 150 user appliances use 384mb ram and run just fine.
if you have less than that, I can't see you even running an os.
our 100 user VPS clusters allocate ~512MB ram to each instance and see
to work just fine.
(I say ~512MB because of the 'above the clouds' type virtualization we
use can 'rob' ram from other idle VPS's when needed and give it back later)
(the hosted 100 user virtual systems need more ram than the 150 user
appliances since they need to replicate data)
no substitute for ram when it comes to a ram intensive program like perl
(which runs amavisd)
if using db4 to run awl and bayes, limit its usage. (you can set ram
usage in db4), or use db2. maybe don't use AWL.
What else it taking up the ram? run a top. clamav? just use basic
sigs, no sane sigs, no google safesigs.
don't run pyzor, where is the DNS server? you running a caching dns
server on the same box? what about httpd? you limit the starting and
available processes?
postfix (your mta) are you limiting the max number of postfix servers?
cut down on SA rule usage, compile the rules, set bayes to manual
sync/expire and crontab the expire at night when email processing is not
important.
pay for more ram :-)
if that isn't an option, consider alternatives to running amavisd, such
as doing everything in postfix and living with the results.
email me offlist if interested in a commercial alternative.
