Install iPerf 3 on Raspberry Pi

The iPerf is a command line tool that allows to test network performance and speed by sending data traffic from one host to another. This tool supports TCP, UDP and SCTP protocols.

This tutorial shows how to install iPerf 3 on Raspberry Pi.

Install iPerf

Connect to Raspberry Pi via SSH. Execute the following command to update the package lists:

sudo apt update

Next, install iPerf 3:

sudo apt install -y iperf3

Once installation is finished, we can check version of iPerf:

iperf3 --version

Testing iPerf

In order to test, you need to have two systems with iPerf. One system will act as a server, while the other will act as a client. Of course, the server and the client can be on the same Raspberry Pi.

Execute the following command to start server:

iperf3 -s

Server starts to listen client connections.

Connect client to server by providing IP address:

iperf3 -c 192.168.0.48

Output example of server (Ubuntu 20.04):
