# of messages per batch

[Alex Neuman van der Hans]

You can also increase the "queue scan interval", specially on lower-spec 
machines, to something higher. In that case your queues might actually 
fill up enough so that the 30-msg-per-batch default makes MailScanner 
pick up 30 messages out of, say, 100.

On very low volume mail servers, you can even decrease that (I've set it 
to "1" on mine) so that processing is virtually instantaneous.

Sven De Troch spake the following on 11/1/2006 2:24 PM:
There is a setting in the conf file for max messages per batch, but
MailScanner will not sit and wait for messages to pile up. If you are 
running
10 children, and mailscanner is set to check the queue every 30 seconds, 
then
you would have to get something like 600 messages per minute to fill the
default batch size of 30. If you are getting 10 to 20 messages a minute, you
will never even break a sweat with 10 children. That would be around 1-4
messages per batch. You could lower your max children and see if the system
keeps up.
