You should have the socket option > TCP_NODELAY set in your configuration file. See page 493 of "The > Complete FreeBSD", second edition. You're terribly confused :-) they do NOT create "a new TCP connection for every packet" They have the capacity to restart a session at any time, but they do not do so normally. sounds to me as if his enet card is stuffed.. There may be some tunable options that will make samba run better on freeBSD as well but I can't help there.. julian To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
