I would think that TCP offloading techniques like MS TCP Chimney/NetDMA would be necessary to accomplish those high-speed. It will be interesting to see what Iperf3 uses and if it will be suitable to use with MS Chimney (MS Server 2012R2). It took MS nine years to get their technology working well. No need to abandon it now.
One side thought. There will be few services that create 100 Gb traffic flows (weather data, etc). The Iperf2 approach to coordinate multiple traffic flows over multiple computers seems like a good model for typical data services (e.g. 5G backhaul).
