You are right. It is a long time since I have last used iperf3, but now that you have mentioned it I have also remembered this. So the previous poster has misinterpreted the iperf3 results, by believing that UDP was slower, as iperf3 cannot demonstrate a speed difference between TCP and UDP, since for the former the speed is determined by the network, while for the latter the speed is determined by the "--bandwidth" iperf3 command-line option, so the poster has probably just seen some default UDP speed. |

And I am quite sure that UDP is slower, becuase I increase `--bandwitdh` until throughput stops increasing, which is at 20% of TCP's speed.
