If, for some reason, FreeBSD _does_ turn out to be much slower than Linux (which I doubt), chances are something is just tuned wrong. All code I've seen indicates that Linux should be lagging FreeBSD in this area... (and no, reiser doesn't really count since it's not all that reliable yet ... like Matt wrote, it has a long way to go until it reaches reliability) regards, Rik -- Virtual memory is like a game you can't win; However, without VM there's truly nothing to lose... http://www.surriel.com/ http://distro.conectiva.com/ Send all your spam to aardvark@nl.linux.org (spam digging piggy) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
