No need perhaps, but does that prove that no disk I/O takes place? I am
not saying there is disk I/O, but lack of need is not lack of use. So
that should be excluded. If the disk is not saturated, perhaps there
are DNS lookups or other sources of latency.
Tracing the system calls in the milter may help (when sending just
one message to reduce confusion).
