You should temporarily raise $log_level to 2 or 3 and look at the
TIMING statistics for a few messages. On a busy server one of the main
difference with Maia will be the heavy SQL traffic. All else being
equal,
a poorly tuned InnoDB engine would be the first place I look. If you
are using MySQL and have not tuned InnoDB, Maia will perform poorly.
I would also ask if you added Pyzor to the mix. If so, I would not
use the Pyzor main server, I would use the mirror at
82.94.255.100:24441.
Look for the 'servers' file in the .pyzor directory of the home
directory of the amavis user. This alone can save 4 or 5 seconds. Also,
if using Razor, on occasion it's a good idea to re-discover the servers:
su amavis -c 'razor-admin -discover'

Gary,

Thank you for the reply/suggestions. I had the logging on 2 and changed
it to 3 then 4 but could not really see anything that pointed out what
was taking the most time to process besides looking at the log entry
time for each. As for mysql traffic, there isn't a WHOLE lot of mail
going through this system yet (most is still on my plain postfix/amavis
install) and the box that has the mysql db on it is connected to the
same Cisco Catalyst (both ports 100/full). Neither box is under a load
higher than 1 or even close under normail circumstances. I am not super
familiar with SQL, mysql, or tuning InnoDB so I'm not sure if this is my
problem. I did change my Pyzor server to the one suggested and ran the
razor discover but neither changed the process timing in either
direction.

Dylan
