I don't know what options, etc., you are using. I would suggest 1K (1024), so that it will fit in a single packet, even with some extra options set. 1500 is the standard MTU... if it looks small to you, you must have some really whacked-out hardware... and it must violate the ethernet standards. 8-). Feel free to switch to an 8K (8192) or large read/write size, *IF you use TCP instead of UDP*. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-chat" in the body of the message
