Download Jperf 2.0 2 Windows
Melony Kai
Jperf is a script that runs on windows, and takes the place of IPERF.This little GUI should do most of the things you need, from a two windows machines. If you want to do it on Linux, then you can just use the Iperf command line.
After you download it successfully you need to copy the contents of both archives in a own directory (no subdirectory for IPerf and JPerf). Subsequently you have to execute the jperf.bat and the window of JPerf will be started on the Windows system PCs

So basically what i'm trying to understand is how does the representative file work and what are the differences between using jperf to test throughput speed for a file and using network sharing over two windows machines. i.e. will it show any huge difference and if so what are they and why?
I'm checking real throughput of my network using iperf/jperf. Test with speedtest.net shows 25/10 - but jperf shows only 5. So I change in jperf the TCP Window Size into 256K - and now jperf shows 17Mbit - i think it's quite ok, but how to set it permamently? If I restart jperf - and no change of TCP Window - it is again 5Mbit.
So dig the internet and found -2kxp-registry-tweaks-157 -> I set the GlobalTCPWindows and many more. Than restart the computer, and... nothing happens. jperf shows still 5 until I change the jperf parameter into 256K....

I used a quick tutorial from Linhost.info -on-windows/ to get the install going. I had 2 cases I wanted to test. My new laptop to another box on the wireless network and my laptop to a pc on the wired network. (both G and N).
I needed to run iperf on both a windows and a linux box. The install for windows is simply download and run the iperf.exe. On linux I needed to grab the latest release. I am running ubuntu so it can simply be done by running sudo apt-get install iperf
To configure the the server side of iperf you only need to run the command iperf -s (both on linux and windows). To allow this to work on linux I needed to open port 5100. To do this on ubuntu I ran the following command to open ufw.
sudo ufw allow 5100
Este programa está discontinuado, es decir, no tendremos nuevas funcionalidades y la última versión es la jperf-2.0.2. Os recomendamos descargar esta última versión desde este enlace que lleva directamente a Google Code Archive. La última versión es la 2.0.2 por lo que debemos utilizar esta.
Una vez que hayamos descomprimido el ZIP descargado, entramos en la carpeta y hacemos doble click sobre el archivo que pone jperf.bat. Este script hará todo lo necesario para arrancar correctamente el programa y empezar a utilizarlo.
You'll need at least 2 machines, 1 in server role (listening) and 1 as the client. The "server" can be a standard Windows desktop machine. Jperf implements Java, so it must already be installed. Launch jperf.bat and set up the server by selecting "Server", specify a listening port, and click the start button. We don't intend offend, but ensure the following obvious scenario:
Does anyone know of a good LAN speed test program, preferably free. I have tried jperf/iperf and am not smart enough to make it work. I also tried LAN Spped test by Totusoft (www.totusoft.com Opens a new window) which worked and got me started on this quest. However thier free version does not give me the information I want. I would like to know if my clients are transmitting/receiving to their capacity. Any ideas?
I tried the java version (xjperf from sourceforge) but could not get it to work. Launched the server on a remote, the client connected but no transfer or measurements. Can't figure out what i did wrong unless it is a permissions issue on the remote system.
The jperf is written on Java (in order to run jperf, the Java VM must be installed on the computer). In addition to graphical form for the CLI interface, Jperf can build real-time graph bandwidth charts of the communication channel load. To use it, just specify the iPerf server address and start the network throughput test.
