A very slow MS 4.62.2-3 & SA 3.2.1 & ClamAV 0.91 machine

[Quentin Campbell]

I have a very slow mail gateway among the 4 that I have just upgraded.

They all run MS 4.62.2-3, SA 3.2.1 and ClamAV 0.91 and should have identical configurations for MS and SA. MCP processing is done and it is the same on all 4.

There were 211 batches of 30 messages each processed on the slow machine. Overall the average time to process each message is 15 seconds!

The last two of these batches were processed by running MailScanner in debug mode. The average processing time for each message then dropped to between 2 and 3 seconds!

I am trying to get a handle on why this machine is so slow. Any suggestions to help further my investigation are welcome.
