While we find it invaluable, I'm not sure how it fits in here. We use iperf on high-performance systems with a lot of tuning and Myricom 10GE cards to test 10 Gig circuits (10GE or OC-192). No particular endorsement of Myricom. We also qualified Chelsio. At the time we tested, TSO on the Chelsios caused some problems when the other end was a Myricom, but TSO is easily turned off. -- R.
