Userland traffic generators have high overheads with small > packets at Gigabit speeds. I wrote one a long time ago for John Wroclawski (back when 100 Mbit/s was still considered a high speed). I don't think I have the source any more, and even if I did it would require a lot of hacking to make it work (it was fairly intimate with the IP stack in 2.2.5). -GAWollman To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
