I inherited this freebsd mail server. It seemed really slow so I got and ran iozone. It was able to produce something like 600 k bytes/ sec sustained IO. The same hardware in the adjacent rack slot running linux and iozone was able to sustain about 55 M bytes/ sec. So I migrated the server functions and loaded linux to the freebsd hardware. It was then able to match the first linux system in performance. To me a factor of 100 performance is a pretty important bug. This server was barely able to handle 5 simultaneous deliveries under qmail. Now it handles 50 simultaneous deliveries and acts like it is doing zero. Maybe freebsd should back off a notch on the security thing until they get the basics working. Other than things like that security is very important. But then I'm not a fair judge on that topic. ;)

FreeBSD aren't the security gestapo, that's OpenBSD. My guess is that your performance problems were related to filesystem configuration. Most places see similar performance between FreeBSD or Linux, with the former often outperforming the latter.
