I've been working on this a bit and the only way to get it was to run multiple iperf3 threads. To do this, you have to set up several (we do about 8 threads for 100Gb, possibly 10) on the target (listening to different ports) and then run to client instances (one for each port), then aggregate the results for each, and that nets in the 92-97Gb/s range overall.
Additionally, in some cases tweaks are necessary (jumbo frames, some kernel tweaks, driver tweaks, etc) but that's all case-by-case. And it is very much constrained by CPU and PCIe bandwidth.
