In Windows operating systems, QoS Policy combines the functionality of standards-based QoS with the manageability of Group Policy. You can spin up a quick EC2 VM running in Amazon EC2 and only have this running for the duration of the test, after which you can power down and terminate the instance.įirst, let’s setup iPerf3 on the Amazon AWS EC2 instance.In addition to this topic, the following QoS Policy management documentation is available. One of the easiest ways to do this is to spin up an EC2 instance. To effectively see what kind of Internet bandwidth you are getting, you need to have a server on the Internet. Just make sure you are running iPerf or iPerf3 on both server and client.
In other words, you can have the server running on Linux and the client on Windows or vice versa. What I like to do that is simple and easy is spin up a quick EC2 instance, load iPerf, and then setup a quick security group rule that is scoped down to my home IP.Īlso, as a note, you don’t have to run iPerf on the same platform. Obviously, one will be at your home or in the home lab environment.
With that being said, you need a couple of nodes. This is what I really like about iPerf compared to simply visiting a speed test type site. While the premise is simple, it provides a very accurate way to measure the real-world bandwidth between two different nodes. Based on this exchange of data, the bandwidth can be calculated between the two nodes. The client sends data and the server listens for data to be sent. One node serves as the server node, and the other node serves as the client node. New: Disk write tests (server: iperf3 -s -F filename / client: iperf3 -c testhost -i1)īasically iPerf works under the premise that you have iPerf loaded on two nodes.New: Disk read test (server: iperf3 -s / client: iperf3 -c testhost -i1 -F filename).New: Output in JSON format (-J option).New: Use SCTP rather than TCP (–sctp option).New: Set congestion control algorithm (-C option).New: Set target bandwidth for UDP and (new) TCP (-b option).New: Ignore TCP slow start (-O option).A server accepts a single client simultaneously (iPerf3) multiple clients simultaneously (iPerf2).Use representative streams to test out how link layer compression affects your achievable bandwidth (-F option).Print periodic, intermediate bandwidth, jitter, and loss reports at specified intervals (-i option).Can run for the specified time (-t option), rather than a set amount of data to transfer (-n or -k option).The server handles multiple connections, rather than quitting after a single test.Client and server can have multiple simultaneous connections (-P option).Cross-platform: Windows, Linux, Android, MacOS X, FreeBSD, OpenBSD, NetBSD, VxWorks, Solaris,….The client can create UDP streams of a specified bandwidth.Support for TCP window size via socket buffers.Report MSS/MTU size and observed read sizes.As a note, it is not compatible with the original iPerf tool. The latest version of iPerf is denoted as iPerf3. The iPerf tool allows measuring bandwidth, loss, and other parameters. The iPerf tool is a command-line tool for actively measuring your maximum achievable bandwidth on a TCP/IP network.

Let’s look at how to use iperf to test internet speed and see how you can set up this type of test. Aside from using the commercial “speed test” type sites, I encourage you to use a well-known tool called iperf. If you are like me, you depend on the home lab to a large degree, even using it as a testing ground for production technologies, presentations, and other things. However, it is still a good idea to trend these types of things in your home lab especially. SLAs in terms of residential connections are much more liberal as well, unfortunately. Residential connections are generally quite a bit flakier in terms of fluctuations you see in available bandwidth and other metrics. It is important to check your Internet speed as you want to make sure you get what you pay for in terms of bandwidth.
