Network Throughput Testing

I ended up upgrading the wiring in my place to CAT7 recently and I wanted to see if there was a noticeable performance difference to my previous cabling. This blog post won’t be a product comparison, but instead I’ll show how you can do network throughput testing at your own location.

There is a great package called iperf3. It’s in most repositories under Linux, and binaries for Windows and macOS exist as well.

For a more in depth tutorial check out this post from Linode.

For the 5 second spiel…

One one machine, start the server

iperf3 -s

On another machine connect to the server and begin testing the connection

iperf3 -c

You can also use the -t flag to specify the number of seconds you want to run the test for.
