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 `iperf`. It's in most repositories under Linux, and binaries for Windows and macOS exist as well.

One one machine, start the server
```bash
iperf -s
iperf3 -s
```
On another machine connect to the server and begin testing the connection
```bash
iperf -c 192.168.0.2
iperf3 -c 192.168.0.2
```
You can also use the `-t` flag to specify the number of seconds you want to run the test for.
