Rather advanced stuff, but a method for tweaking kernel behaviour on the fly. man sysctl should give you a basic overview of what is going on with the sysctl command. There are a lot of sysctl variables, and I don't know of any comprehensive guide as to what each one does, but setting net.inet.tcp.delayed_ack=1 was what I saw recommended as a solution for poor performance. -Bill To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
