Performance

[John Schmerold]

We're seeing significant backlogs, mail is taking 2-6 hours to get thru 
the Postfix/Mailscanner gauntlet we've setup. What's everyone else 
seeing in terms of mail processing time?

I've looked at the home page & WIKI, so, I'm guessing I am missing 
something or there are new techniques not yet published on the 
mailscanner.info

Some of my statistics are as follows:
Server config: 2.8GHz P4, 2GB DDR2, Maxtor SATA HDD
Mail volume: approx 7,500 messages per day
Misc: We have set the noatime flag on spool and log partitions & use a 
local DNS caching nameserver.
