Without that kind of information I'm not too comfortable giving advice on tuneables because I DON'T KNOW WHAT I'M TUNING :), when I've just blindly told people to increase NMBCLUSTERS they've had other problems because the kernel's network buffers wired down all the machine's memory. Yes, increasing NMBLCUSTERS is a good thing, but without your configuration it's hard to say how much to increase it. -- -Alfred Perlstein - [bright@wintelcom.net|alfred@freebsd.org] To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
