I did a quick test with iperf on 100 G environment and 40 G
environment, in summary rsocket works pretty well.
iperf tests between 2 hosts with 40 G (IB),
first a few test with different num. of threads on top of ipoib
interface, later with preload rsocket on top of same ipoib interface.

You can see with rsocket it reaches ~ 30 Gb/s with single stream,
while ipoib only 2.5 Gb/s (12 X), ipoib scales with more threads until
~ 32 Gb/s, which is the link limit.
With 100 G env, rsocket also out perform ipoib, see below:
