Hope this helps. I'm probably on the lunatic fringe but I have my maxservers set to 50 on my amavisd servers and the max connections from my postfix servers set to 50. There are three of each type of server so the total max connections 150. In this configuration my average per process amavisd idle time is roughly 20 seconds although sometimes it creeps down to 8 seconds. The average processing time is around 6 seconds. The servers are overkill (dual CPU 1.2GHz ultra Sparc III's with 8GB of Memory) but they do the job nicely.
This was done to avoid the postfix-amavisd connections from being the bottleneck. There are other bottlenecks, but at least this isn't one of them. Before this configuration, the max servers was set at 20 but the max outgoing connection was set from postfix was set at 7. Cranking up the postfix was the major trick. Although it isn't supposed to help if you have more than 20 servers, it doesn't hurt as long as you have enough memory and more than one CPU. I like to keep the idle time of the amavisd processes relatively high so that I can deal with traffic such as public events sending its weekly e-mail to the entire campus. Hope that helps. ---Jack Mark Martinec wrote: > >> I have had my $max_servers anywhere from 4 to 20 with this behavior. >> Is there perhaps something I should change with max_requests to help this >> out?
