The issue is mostly just that the various paramters tend to be pushed around to suit the behaviour of a given system, and that doesn't really tend to follow the "generic" application of a system much. > And does anyone know how these parameters are tuned in NetBSD and > OpenBSD?

OpenBSD/NetBSD use the static configuration like we used to; the boot-time tunables are my recent additions. -- \\ Sometimes you're ahead, \\ Mike Smith \\ sometimes you're behind. \\ mike@smith.net.au \\ The race is long, and in the \\ msmith@freebsd.org \\ end it's only with yourself. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
