Regarding the "few milliseconds" -> are you sure that we are talking
abust "just a few" of them? Time ago I dedicated 1 GB tmpfs to each
Amavis Host, and it seemed that this really improved I/O performance.
However, I did not run any benchmarks proving this.

Cleanup cronjobs are running each night and removing files older than
2 days. Max allowed mail size is 100MB, 40 Amavis processes on each
host. I never noticed tmpfs filling up, I'm not even monitoring it.
However, if my front MX servers queue is filling up, immediately at
least two people get a notice.

Regards,
Thomas
