No. As I specifically said, the GENERIC kernel configuration is tuned for 'generic' operations. There are a small number of well-known and well-documented tuning options that need to be adjusted to accommodate the sort of extreme load situations you're encountering. You might want to think, just for a moment, why FreeBSD is in such wide use if the assumptions you're making are true. And since it is, perhaps you should re-evaluate them? -- \\ Give a man a fish, and you feed him for a day. \\ Mike Smith \\ Tell him he should learn how to fish himself, \\ msmith@freebsd.org \\ and he'll hate you for a lifetime. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
