I'd assume in this case the iperf "server" is linux or did Jack add IPv6 LRO support to e1000? Sorry, I am not up-to-date. However, any modern peice of hardware should be able to fill the 1G link even with software doing csums or offloading really and all our routing table lookups. What's the well known FreeBSD machine of a machine? I can only imaging what's going on for you and some of the latest work was not yet merged to head or 9; I have 1 or 2 patches posted to net@ for review and testing though. Sorry not immediately helpful. /bz -- Bjoern A. Zeeb You have to have visions! Stop bit received. Insert coin for new address family.
