You might want to look here (although it is a bit old by now) http://forums.devshed.com/bsd-help-31/freebsd-openbsd-netbsd-darwin--the-definitive-answer-73907.html For the masses: - NetBSD: Run on any hardware (including toasters) - OpenBSD: Be as secure as possible - FreeBSD: provide best system for x86-platforms This might be the reason why generally speaking OpenBSD is recommended for network tasks (where security matters), FreeBSD for server tasks (especially on x86-systems) where the application must be available (very large ports collection), and NetBSD for every hardware that isn't mainstream. But because we always see code exchange between the BSD systems where appropriate, all systems get more secure over time, support more platforms, etc. http://en.wikipedia.org/wiki/Comparison_of_BSD_operating_systems http://en.wikipedia.org/wiki/Comparison_of_open_source_operating_systems Afaik MP-support in OpenBSD is much less optimized than in FreeBSD, especially as FreeBSD got rid of Giant Lock in most places since some time already. There are also old benchmarks available (2003), so this is mostly interesting from a historical point of view: http://bulk.fefe.de/scalability/ You might also want to check http://forums.2cpu.com/archive/index.php/t-17014.html http://people.freebsd.org/~kris/scaling/dfly.html http://people.freebsd.org/~kris/scaling/7.0%20and%20beyond.pdf for further information. > Thanks :-) Regards, Holger
