PS: Am I right that the TCP_RR tests should only be run on a single node at a time, not on both ends simultaneously?
It depends on what you want to measure. In this specific case since the goal is to saturate the link in both directions it is unlikely you should need a second instance running, and if you do, going to a TCP_STREAM+TCP_MAERTS pair might be indicated.
If one is measuring aggregate small transaction (perhaps packet) performance, then there can be times when running multiple, concurrent, aggregate TCP_RR tests is indicated.
Also, from time to time you may want to experiment with the value you use with -b - the value necessary to get to saturation may not always be the same - particularly as you switch from link to link and from LAN to WAN and all those familiar bandwidthXdelay considerations.
