What should I do? I'm seeing quite a bit of unexpected UDP loss. Why? First, confirm you are using iperf 3.1.5 or higher. There was an issue with the default UDP send size that was fixed in - 3.1.5. Second, try adding the flag ``-w1M`` to increase the socket + 3.1.5. Second, try adding the flag ``-w2M`` to increase the socket buffer sizes. That seems to make a big difference on some hosts. -iperf3 UDP does not seem to work at bandwidths less than 1Mbps. Why? +iperf3 UDP does not seem to work at bandwidths less than 100Kbps. Why? The pacing algorithm used by iperf3 does not allow for send rates - less than 1Mbps. + less than 100Kbps. What congestion control algorithms are supported? On Linux, run this command to see the available congestion control
