Iperf is a commonly used network testing tool to help measure network throughput
Iperf is an open source tool. There are clients for Mac, Linux, BSD, etc. There is a port for Windows; however, in our testing we found it to lack certain features and to lag in performance.
Iperf operates where one end is the client, the other is the server. WiscNet runs an Iperf version 2 server in Eau Claire, WI
The server is restricted to WiscNet IP addresses
Iperf2 and iperf3 are incompatible
iperf.wiscnet.net runs a TCP Iperf server on the default port 5001
iperf.wiscnet.net runs a UDP Iperf server on port 5001
iperf.ipv6.wiscnet.net runs a v6 TCP Iperf server on port 5001
iperf.ipv6.wiscnet.net runs a v6 UDP Iperf server on port 5001

WiscNet has noticed that the Iperf clients for Linux, Unix, and macOS perform better than the ports for Windows
