Just looking at a BSDI 3.1 system that I've just installed qmail on, and I must say it screams. My "gut-feel" is that it's much faster than Solaris and FreeBSD on equivalent hardware. The qmail-remotes come in at 118K which means from a memory perspective I can wind up concurrencyremote at almost no cost. I know the BSDI dudes are pretty good, but I was always under the impression that FreeBSD led the way on performance. Anecdotally I might have to re-arrange this perception. Leastwise for qmail. Regards.
