 ====== iPerf ======
-**IPerf** is a tool which allows you to measure and tune network performance.  IPerf can be run in client mode or server mode. Generally, client mode is used. iPerf requires you to know of a reliable public server with which to use it. Currently, the official IPerf webpage hosts a short list of public iPerf servers: [[https://iperf.fr/iperf-servers.php|https://iperf.fr/iperf-servers.php]].

-Some iPerf server don't work, so if you receive an error when testing, try a different iPerf server. You can also try unofficial iPerf servers, but their location and availability may often change. Once you've configured the Server address, protocol and port, you can start your tests. You'll probably only use Server mode if you're testing an intranet VPN site.

+===== iPerf Notes and Troubleshooting =====
-Unfortunately, there are currently few reachable iPerf servers. It's important to use an iPerf server with geographical proximity to get accurate results. The above example was run on a 200Mb downstream / 12Mb upstream connection. However, as you can see, the results are far from accurate. Regardless, the IPerf tool can still be useful for things such as intranet VPN performance testing and tuning.
