![]() ![]() ![]() Once we have iperf, we need to learn how to use it. If you don’t do that, you will need to move to the folder where you have iperf before you can give the command. This way, you will always have iperf3 at hand as a command on the prompt. Extract it, and if you want to do things faster copy its content into C:\Windows\System32. If you are on Windows like me, you will get a compressed ZIP file. In this guide, we are using iperf3 on Windows (64 bit), but the tutorial on how to use iperf is the same for any OS. You will find an iperf for any operating system and architecture you need. In a rush? Here is a quick link to the download page. It is free software (BSD license) you can download from. Since you place the server whenever you want, you can also have it on your internal network and thus test internal links. This means you won’t be able to reproduce the same test in the future if you do an online speed test. That’s not the case with online services, where they allocate you a server dynamically. ![]() You know where the server is, and you may repeat the test in the future. The advantage of running your own server is predictability. In fact, you can have both the server and the client on the same computer. Don’t worry, you don’t need special hardware, you only need to run a command from your prompt. Instead, with iperf, you have to set up your own iperf server. Then, the application measures the network performance between you and such a server. In other words, when doing an online speed test, you connect to a server on the Internet, owned by the provider of the test (like Ookla). Unlike online speed tests, you have to provide both server and client. Iperf is a command-line tool that allows you to test the bandwidth, any way you like. Getting started with iperf What is iperf? In this tutorial, we will see how to use iperf to verify the speed of any link, reliably. That’s why, at the enterprise level, we use iperf (actually iperf3), a powerful and free tool. Furthermore, you can only test Internet speed, and not speed on internal/private circuits. However, those methods are not reliable enough for an enterprise. Popular examples are the Speedtest by Ookla, by Telstra, or by Verizon. If you want to do that at home, you can use many speed test services. When you buy an Internet link, you want to see if you get what you’re paying for. ![]()
