+Some iPerf servers don't work, so if you receive an error when testing, try a different 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.

-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. Nevertheless, the IPerf tool can still be useful for intranet VPN performance testing and tuning.

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