Ever wanted to see what the network quality was between two points? This is easy with iperf3!

You can easily test network traffic between two nodes anywhere in the world, as long as the server is publicly addressable (i.e. the server has a public IP address or you've set up port forwarding on your router).

This is so easy to do, that I now do regular tests with all my different nodes. Having a basic idea of the network throughput capabilities of each node leads to much better decision making!

Interested? Install iperf3 on both the client and the server, and follow along! If you are using Fedora or RHEL derivatives:

sudo dnf install -y iperf3

Ubuntu or Debian:

sudo apt install -y iperf3
