iperf-s [options] iperf-c server [options] iperf-u-s [options] iperf-u-c server [options] DESCRIPTION iperf is a tool for performing network throughput measurements. It can test either TCP or UDP throughput. To perform an iperf test the user must establish both a server (to discard traffic) and a client (to generate traffic).

There was an issue with the default UDP send size that was fixed in 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 100Kbps. Why? To verify it's not a case of the tunnel itself, a test with iperf2 performs correctly: # iperf -u -c 10.8.1.1 -b 100M ----- Client connecting to 10.8.1.1, UDP port 5001 Sending 1470 byte datagrams UDP buffer size: 122 KByte (default) ----- [ 3] local 10.8.1.6 port 33252 connected with 10.8.1.1 port 5001 [ ID] Interval Transfer Bandwidth [ 3] 0 IPerf is an open-source tool designed to test network bandwidth between two network nodes.
