Iperf is a great networking tool for performing end-to-end throughput tests. These tests can be layer two or layer three. But as simple the use of Iperf is, it is only popular among experienced network engineers. In this post, we will look at how to install and use Iperf on Windows for throughput test.
The Iperf tool is a freeware that can be run as executable file either in server or client mode. It is purely command line and that explains the reason why only a few people use it. The process is fairly thesame for other versions of Windows. If you are downloading for a Windows computer, click on the first option named Iperf for Windows.
Now, by default, it goes into your download folder. To simplify the execution process, copy the Iperf folder from your download folder to your desktop and unzipped the folder to extract the executable file named iperf3.
To run the Iperf executable file, open the command prompt. Next, change your directory to the directory housing the Iperf folder. See image below. Since I have another folder named Iperf, I will furthermore change my directory to Iperf once more. Now, what is left is the executable file named iperf3. See image below:. On the client side, simply use the command as shown in the image below to run Iperf in client mode. Note that the IP address on the server side must be included in the command.
From the result of the test, can see the bandwith available to us at different Megabytes of data transferred. The average is Video: How to add, monitor and manage hosts using the Mikrotik Dude.

However, before you can go into actual tuning, you need to perform some tests to gather overall network performance statistics that will guide your tuning process. Its results include time interval in seconds, data transferred, bandwidth transfer rateloss, and other useful network performance parameters.
It is primarily intended to assist in tuning TCP connections over a particular path and this is what we will focus on in this guide. Before you start using iperf3you need to install it on the two machines you will use for benchmarking. Since iperf3 is available in the official software repositories of most common Linux distributions, installing it should be easy, using a package manager as shown. Once you have iperf3 installed on both machines, you can start testing network throughput.
First connect to the remote machine which you will use as the server and fire up iperf3 in server mode using -s flag, it will listen on port by default.
If port is being used by another program on your server, you can specify a different port e. Optionally, you can run the server as a daemon, using the -D flag and write server messages to a log file, as follows. Then on your local machine which we will treat as the client where the actual benchmarking takes placerun iperf3 in client mode using -c flag and specify the host on which the server is running on either using its IP address or domain or hostname.
After about 18 to 20 seconds, the client should terminate and produce results indicating the average throughput for the benchmark, as shown in the following screenshot.Srilanka hot kello
Important : From the benchmark results, as shown in the above screenshot, there is a variation in values from the server and client. But, you should always consider using the results obtained from the iperf client machine in every test you carry out.
There are a number of client-specific options for performing an advanced test, as explained below.
One of the important factors that determine the amount of data in the network a given time is the TCP window size — it is important in tuning TCP connections. To run it in reverse mode where the server sends and the client receives, add the -R switch. To run a bi-directional testmeaning you measure bandwidth in both directions simultaneously, use the -d option. If you want to get server results in the client output, use the --get-server-output option.
It is also possible to set the number of parallel client streams two in this examplewhich run at the same time, using the -P options. Remember to always perform network performance tests before going for actual network performance tuning.

For the sake of example, we will be setting up two instances of the Amazon Linux AMI, but feel free to skip the following Instance Setup section if you already have two instances set up. If you want to follow along, check out the Live Lab for this guide provided by Linux Academy.
After accepting the fingerprint, you will be logged into the instance via SSH in your terminal window. Starting the server Use the details from your connection window to connect to the instance be sure to use your instance hostname instead.
Open a second terminal window to connect to our iperf-B instance. Since we are using the same key for both, we have already ensured the iperf-keypair. Accept the fingerprint, then install iperf3 on this second instance, just as we did on the first again, watch the output. Now we are ready to run iperf3 on the second instance and test the bandwidth between the two.
We will instruct it to run a test using the IP address of the iperf-A instance recall that we have the server running on port X with the IP address of the iperf-A instance you just located.
The reported speeds may vary between subsequent tests, but they should give you a fairly accurate idea of your possible bandwidth between instances to help identify possible bottlenecks in your infrastructure. I will also rename my instances to that I can easily distinguish between them, and I suggest you do the same.
Name one instance iperf-A and the other iperf-B. To get connection details on AWS, check only the desired instance iperf-A and choose the Connect button above the list. Following the details on the connection popup, we must first ensure that the keypair we downloaded earlier is not publicly viewable.To perform an iperf test the user must establish both a server to discard traffic and a client to generate traffic. On your other machine, connect to one machine and replace it with the server machine IP.
The -u option tells Iperf to use a UDP connection. The output is as follows: You will see the following output on the server:. Iperf needs to be installed on the two servers you want to test the connection to. Iperf needs to play client and server roles on the two machines.

Advanced Package Tool, or APT, is a free software user interface that works with core libraries to handle the installation and removal of software on Debian, Ubuntu and other Linux distributions. APT simplifies the process of managing software on Unix-like computer systems by automating the retrieval, configuration and installation of software packages, either from precompiled files or by compiling source code.
Each package is a package name, not a fully qualified filename.
All packages required by the package s specified for installation will also be retrieved and installed. If a hyphen is appended to the package name with no intervening spacethe identified package will be removed if it is installed.
Similarly a plus sign can be used to designate a package to install.
