WebiPerf3 is a tool for active measurements of the maximum achievable bandwidth on IP networks. It supports tuning of various parameters related to timing, buffers and protocols (TCP, UDP, SCTP with IPv4 and IPv6). For each test it reports the bandwidth, loss, and other parameters. This is a new implementation that shares no code with the original ... Web1. udp is a best effort protocol so iperf probably doesn't check that the packets actually arrived. Also -b sets "bandwidth to send at in bits/sec or packets per second" which you set at 500M. So I think you're just testing that your nic driver can send at 500Mbps.
