owamp is a latency measurement tool. 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.
