Not only configuration. A friend of mine upgraded a computer that was
unable
to handle the mail feed from P200 to PIII 800 going from sendmail to
qmail at
the same time. The load average dropped from "allways very busy" to
0.02.
It is possible that it is mainly from better conf and faster processor
but then
I'd claim that qmail is easier to configure for big load.
