In this article youll find how to test Internet speed from the Linux terminal, using speedtest_cli a simple command-line client written in Python for measuring Internet bandwidth by using Speedtest.net infrastructure. By default, iperf communicates over port 5001 when testing UDP performance. Iperf can be used in two modes, client and server. If you want to test your Ethernet LAN at a lower level you can use Etherate which is a free Linux CLI Ethernet testing tool: https://github.com/jwbensley/Etherate. This utility continuously sends TCP and UDP data streams across your network and computes You can move the virtual machines to different physical servers, jump around on different VLANs, or because they are so small, move them to the DR locations to spot-check network performance. Function: TTCP. Add the -n parameter to sar to view network statistics, such as network interface Expected outbound throughput and the number of network interfaces supported by each VM size is detailed in Azure Windows and Linux VM sizes. Lets test the throughput from the Linux client machine, as shown below. Before You Start, Install EPEL; Command-Line Network Monitoring on Linux. Use version 2.x network throughput test tool.
