Lets test the throughput from the Linux client machine, as shown below.
#Sysinternals lan speed test windows#
The above command, starts iperf server on the windows machine, and it bydefault runs on the port 5001 by default.(It also reports that the default TCP window size is 64.0KB).
S argument is used for specifying server We will make our windows machine the server and the Linux machine as the client. Suppose you have a windows machine and want to measure the speed between it and another Linux machine, then you need to make one as client, and another as the server. So you can clearly see that, if you increase the Window size a little bit to tune TCP, it can bring significant difference to the throughput achieved. Which means for sending the whole 500MB data, the sending machine has to wait 800 times for an acknowledgement from the receiver. Suppose you want to send a 500MB of data from one machine to the other, with the tcp window size of 64KB. This TCP window size affects network throughput very badly sometimes. In other words, the maximum amount of data that a sender can send the other end, without an acknowledgement is called as Window Size. Whenever two machine's are communicating with each other, then each of them will inform the other, about the amount of bytes it is ready to receive at one time. TCP works on a reliable manner, by sending messages and waiting for acknowledgement from the receiver. How TCP works, is beyond the scope of this article. TCP (Transmission Control Protocol), is a reliable transport layer protocol used for network communications. Its measured in Kbps(Kilo bits per second),Mbps(Mega bits per second),Gbps(Giga bits per second.) Throughput is considered a quality measuring metric for hard disks,network etc.
Transfer rate of data from one place to another with respect to time is called as throughput. Normally in the test environment, iperf client sends data to the server for the test.īefore going ahead with the test, lets understand some networking concepts related to speed test. The commands for using iperf on windows is exactly the same as in linux. The operating system does not matter, while you are using iperf.
#Sysinternals lan speed test how to#
C:\>cd C:\iperfĬ:\iperf>iperf.exe How to test the network speed between one windows machine and a linux machine?Īs i told before, iperf can be used to perform speed test between remote machine's.
#Sysinternals lan speed test zip file#
Now unzip this zip file to a folder named "iperf" and run the iperf.exe inside that directory.įor example i have extracted, the iperf zip in C:\iperf directory, so will open the Windows CMD, and navigate to that directory, to run the iperf.exe command.
#Sysinternals lan speed test download#
You can download iperf for windows from Iperf For windows. Installing iperf in windows is also quite easy.
#Sysinternals lan speed test install#
iperf-2.0.5]# iperf-2.0.5]# make install How to install iperf in windows machine? Now lets compile it with "make" command, and then install it using "make install" command. Now get inside the extracted directory and run the below command to configure, with the default options. The above command will extract the tar package You downloaded from the above link. Just download the iperf source package from Iperf Source PackageĪnd do a normal source installation steps as follows.
Installing iperf from source is also very much easy. Installing iperf is very much easy, if you have epel yum repository enabled(in redhat system's). Iperf is much more reliable in its test results compared to many other online network speed test providers.Īn added advantage of using IPERF for testing network performance is the fact that, it is very reliable if you have two servers, both in geographically different locations, and you want to measure network performance between them. IPERF is an open source tool that can be used to test network performance. This post will be concentrating on one such tool called as "iperf". All these requires a reliable network performance testing tool. Also sometimes you need to double check the speed of your network throughput while troubleshooting. Testing network performance in terms of speed and bandwidth is a norm in both production and non-production environment.Ī detailed report of speed and bandwidth analysis is very much necessary for the deployment of network dependent application servers.
