When SMTP transactions are measured in seconds, "faster" really
doesn't matter unless you're talking about how quickly you can
fail a bad connection. The big win with Apache::Qpsmtpd over
forkserver at Apache, IIRC, was in measuring the ratio of forks
to connections. With forkserver, the ratio is 1-1, whereas
with Apache::Qpsmptd it's configurable within httpd, and for
apache is on the order of 1 fork per 5000 connections.
Is there evidence that the forks (and subsequent COW) have a significant
effect on latency - i.e. how quickly you can fail a bad connection?
