Advanced content filter performance

With the "sandwich" approach to content filtering described here, it is important to match the filter concurrency to the available CPU, memory and I/O resources. Too few content filter processes and mail accumulates in the active queue even with low traffic volume; too much concurrency and Postfix ends up deferring mail destined for the content filter because processes fail due to insufficient resources.

Currently, content filter performance tuning is a process of trial and error; analysis is handicapped because filtered and unfiltered messages share the same queue. As mentioned in the introduction of this document, content filtering with multiple Postfix instances will be covered in a future version.
