I told you to wind up the socket's receive buffer size with the approproate socket option in the user app. I don't know what the _real_ "right" answer is for UDP. For TCP, you can try setting the pipe size for the route to tweak the socket buffers. -- \\ 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
