 amavisd performance.
I've run some more tests, and I suggest the following changes (which will become the new defaults):
set log_level to 1 in amavisd.conf.in
set max_servers to 10 in amavisd.conf.in
set smtp-amavis processes to 10 in postfix/conf/master.cf:
smtp-amavis unix - - n - 10 smtp
Restart postfix and amavis.
This will cut down on the IOWAIT on the mta, which is what seems to be the biggest throttle.
If you want the absolute maximum performance from amavis, you can set the log_level to 0, but you'll lose the AS/AV info from the logs (which we use in message tracing). |
