That's a great point. This was one of my iPerf3 runs at one point:

`iperf3 -c 172.31.45.187 -p 5201 -P 128 -t 5 -b 512M -u -l 1448 --bidir | grep "\[SUM\]\[\(TX\|RX\)-C\].*receiver"`

We're also looking at using packet generators to test raw packet throughput. There's a lot more bottlenecks we can cleanup I'm sure.
