Was one of the earliest apps covered at this blog (second only to ) and I still happily use it. Strangely, until recently I had completely missed JPerf utility that equips Iperf with graphical interface to escape horrors of setup.What it doesIf you are not acquainted with Iperf – it is one of the most flexible tools to run bandwidth test, although somewhat limited by being command line utility.JPerf comes equipped with Iperf and its only goal is to take command line out of setup picture.It lists all of extensive options available for running Iperf in either or client mode. In addition console feedback is shown in interface as well and there is graph that plots in real time when test is running. Strong featuresAside from ease of setup it is also important that you don’t need JPerf on either or both sides of the pipe.
It shows command line for settings you chose and that can be easily used with Iperf on its own.Makes it easier to bear command line but doesn’t cut advantages of using command line. DownsidesApp is little clunky and is served in form of Java applet. Is required for it to work and launching app is handled by provided BAT file. Not something you see a lot lately.:) OverallKeeps advanced (if not unmatched) functionality of bandwidth tests and complements with decent setup usability.Download Related Posts. @ RarstThanks for your reply.What do you mean “Don’t have Ubuntu Virtual Machine ready to test at moment”?I install virtual machine to try ubuntu server.
But for instalation jperf package, I use my main machine (Ubuntu Desktop).I have done jperf installation that you have suggested.But I still not install jperf, although I can install iperf beforeResult of error:root@achilles:/home/ariesta/Desktop/jperf-2.0.2#./jperf.shbash:./jperf.sh: Permission deniedroot@achilles:/home/ariesta/Desktop/jperf-2.0.2# sudo./jperf.shsudo:./jperf.sh: command not found.
How to Use JPerfJPerf stands for Java Perf; it’s a GUI for running iPerf without having to bother learning the Command Line Interface (CLI) options. JPerf is a convenient tool to have in your belt. In this post you’ll learn how to use it and a trick to update it to the latest version.
Be sure to note that JPerf supports iPerf version 2, and not the latest iPerf version 3.First of all let’s see how to download it and launch it on Windows and MAC OS.Jperf on MAC:. Download JPerf.
Double-click to untar. From the Terminal navigate to the untarred directory. chmod +x.
brew install iperf. In the terminal run./Jperf on Windows:. Download JPerf. Unzip.
Move to directory and click on jperf.batIf everything goes as planned, you should see this JPerf window: JPerf UpgradeJPerf is just a wrapper for the iPerf executable that comes in the zipped file. By default, when you download JPerf, you get iPerf version 1.7.0 which dates back to 2003. Although optional, it’s a good idea to upgrade to a newer version of iPerf. Here is how to do that:. Download iPerf 2.0.9. Unzip the iPerf bundle in a directory.
Copy all the unzipped files of iPerf 2.0.9 and paste them in the bin directory of JPerfIn more detail, here are the files that need to be copied from the unzipped iPerf 2.0.9 directory:Here is how the jperf-2.0.2-win64/bin directory originally looks:And here is what it looks like after copying the iPerf 2.0.9 files in it:You will need to replace the old iperf.exe with the new one. Now when you run JPerf, you will be using iPerf version 2.0.9 from 2016 and not the outdated 1.7.0 version from 2003.Now, let’s get to some action! JPerf ServerObviously, the principles of JPerf follow those of iPerf: you need two hosts to send and receive traffic. You can use JPerf to set up two different laptops (as a client and a server) to send traffic between them. First, you have to start the JPerf server in order to listen for incoming traffic:. Open JPerf by clicking on jperf.bat.
Choose the “Server” option and the port to listen to (in red below). Click the “Run Iperf!” button (in blue below)(If prompted by Windows to allow inbound traffic, then click “Allow Access”). In green, you can see the command that is needed to run the same server on the command line interface.When finished, you can stop the JPerf server from running on the laptop by using the “Stop IPerf!” button.
Install Iperf3 On Windows
JPerf ClientNow that the JPerf server is listening, it’s time to hit it with some traffic. On another laptop follow these steps:. Open JPerf by clicking on jperf.bat. Choose the “Client” option. Input the IP and the port of the JPerf server (in red below). Click the “Run Iperf!” button (in blue below)Note that there has to be a route from the JPerf client to the JPerf server, and the port has to be open to receive traffic.If everything goes well, you should see a plot like this one:Congratulations!

You have successfully run a JPerf bandwidth test!Since JPerf uses iPerf on the backend, you can combine JPerf with iPerf. You can do this by running it on Linux or any other operating system as a server or a client.Of course, JPerf/iPerf gives you a tone of options that you can tweak when you run your tests.
