![]() ![]() The port of iPerf 3 can also be specified by the -p parameter. If you only use iperf3, you can just open port 5201 only. 5001 is for iperf and 5201 is for iperf3. Open the management page of host B on Azure, enter "Networking" tab, and add TCP 50 ports. Therefore, we need to open the iPerf3 port on host B to allow the connection. What we want to test is the connection speed from host A to host B. We need to install iPerf3 on both server A and server B. Taking Ubuntu Server as an example, iPerf3 can be installed via apt: sudo apt install iperf3 IPerf3 can be installed on Windows and most mainstream Linux systems. We need to start the server on server B, start the client on server A, and initiate a connection from A to B to test the network speed. It uses different parameters to act the role of client or server. iPerf itself does not distinguish between client and server. We need to install the iPerf software on both machine A and machine B (the latest version is called iPerf3). ![]() Suppose you need to test the connection speed of host A to B. And iPerf is a professional network speed test tool that can be used to test the network connection speed between two machines on the LAN or the Internet, so that you can better understand the network performance in your network infrastructure. Therefore, it is very important to know where your network performance bottleneck is. In some scenarios, the final Internet speed is also affected by the your infrastructure like the connection to your ISP's server. But in fact, just testing the Internet connection speed is not reliable. When it comes to measuring network speed, you might think of testing the Internet connection speed with the famous speedtest. Simple concept and easy to use.Original Edi Wang Tuesday, August 4, 2020 ![]() For more advanced users, you can test to LAN Speed Test Server instead of a shared folder to take the slower hard drives out of the process as you are testing from one computer's RAM to another computer's RAM. Next, LAN Speed Test builds a file in memory, then transfers it both ways (without effects of Windows/Mac file caching) while keeping track of the time, and then does the calculations for you. to test the drive speed, or a shared folder on your network to test your network speed. This folder can be on a local drive or USB drive, etc. LAN Speed Test was designed from the ground up to be a simple but powerful tool for measuring file transfer, hard drive, USB Drive, and Local Area Network (LAN) speeds (wired & wireless). only some of the more advanced features are disabled. LAN Speed Test (Lite) is fully functional with no time limits, etc. After installing LAN Speed Test v4, it begins in (Lite) mode. ![]()
