6 to 8 seconds per message ???

Finally have my Maia test config running with 5 IT Dept.
users.

First problem encountered - one of our tech staff had all
Mailer-Daemon bounces routed to his account, which caused
Maia to queue 19,000 messages while it processed them.

Question: What range of time is everyone seeing / or what
should you see with Maia/Postfix to process each/every
message ?

My /var/log/maillog indicates average 6-8 seconds per
message - I believe majority of time is because of
Rayzor/DCC queries.

The server is a P-Dual 3.0 with 512MB of memory. TOP shows
load average is 0.11 

I would expect PostFix to handle messages faster than that
???

Maybe I need to increase the number of threads running
concurrently ???

Thanks

Mike Abraham

Thanks Jeremy

That seems to have provided the key.

Now, it looks like SA check is consuming 97-98% of
processing time for each message. Is this indicating a MYSQL
read issue ???

  I will enable debuging on the amavis side.  If you set it
to verbosity 
  level 2 it will print out timing info.  This will help
narrow down the 
  bottleneck.

It largely depends on the type of checks you do in SA.  If
you use  
the DNSBL checks, make sure you have a good dedicated dns
caching  
server.
Don't use extra SA rules that use lots of memory  (the SARE
BIG*  rules)
