![]() Important: From the benchmark results, as shown in the above screenshot, there is a variation in values from the server and client. $ iperf3 -c 192.168.10.1 -f KĪfter 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. Then on your local machine which we will treat as the client (where the actual benchmarking takes place), run 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). Optionally, you can run the server as a daemon, using the -D flag and write server messages to a log file, as follows. If port 5201 is being used by another program on your server, you can specify a different port (e.g 3000) using the -p switch as shown. You can specify the format ( k, m, g for Kbits, Mbits, Gbits or K, M, G for KBytes, Mbytes, Gbytes) to report in, using the -f switch as shown. How to Test Network Throughput Between Linux Serversįirst 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 5201 by default. Once you have iperf3 installed on both machines, you can start testing network throughput. 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. Two networked computers which both have iperf3 installed.īefore you start using iperf3, you need to install it on the two machines you will use for benchmarking.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. Its results include time interval in seconds, data transferred, bandwidth (transfer rate), loss, and other useful network performance parameters. 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. In order to acquire maximum or rather improved network performance, you need to increase the throughput as well as the latency of your network’s receiving and sending capabilities. It comes in handy for network performance tuning operations. With iperf, you can tune several parameters associated with timing, buffers, and protocols such as TCP, UDP, SCTP.
