Hi ... > I haven't looked at newer versions of ttcp, but the older version, on the > transmitter side, would do a backoff (sleep) whenever it got ENOBUFS from the > kernel. The sleep is tuned for 10Mbps ethernet, so the result is that the > transmitter runs with wild swings filling and draining the kernel's output So this is the part where I go "Oh great master Greenman" :) First off I just removed the delay completely and YES :) the numbers look much better now .. they even increment sequentially from small to large packets ... This will probaly teach me to have a look in the code before I say anything :) Thanx a lot Reinier To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
