To follow up to myself...
* The Internet2 servers are all gigE, and all 9000-byte MTU capable.
* Another thing you could do is tune for the bottleneck instead of gigabit..
150 Mbps = 150*1000*1000 bits * 0.07 ms RTT = 10500000 bits
/8 = 1312500 bytes /(1024*1024) = 1.26 megabytes.
or
100 Mbps is 850K
and see if that improves things. It may be that something can't handle even that much back-to-back when they are sent at 1000Mbps.
There are also bwctl (<http://e2epi.internet2.edu/bwctl/>) servers at Internet2 router nodes, for a different way to split the problem (essentially run iperf to the core).
