How does iperf calculate bandwidth
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. WebSep 9, 2005 · Introduction. You can use the Test TCP utility (TTCP) to measure TCP throughput through an IP path. In order to use it, start the receiver on one side of the path, then start the transmitter on the other side. The transmitting side sends a specified number of TCP packets to the receiving side. At the end of the test, the two sides display the ...
