Monterey Network Quality Tool

Dan Petrov (via Hacker News):

Apple has quietly added a new tool in macOS Monterey for measuring your device’s Internet connectivity quality. You can simply call the executable networkQuality, which executes the following tests:

  • Upload/download capacity (your Tx/Rx bandwidth essentially)
  • Upload/download flows, this seems to be the number of test packets used for the responsiveness tests
  • Upload/download responsiveness measured in Roundtrips Per Minute (RPM), which according to Apple, is the number of sequential round-trips, or transactions, a network can do in one minute under normal working conditions

The capacity is roughly the same metric you could expect from tools like Fast.com from Netflix, or OOkla’s Speedtest.

Update (2021-11-24): Jason Snell:

I’ve written a small SwiftBar plugin (requires python3) to run networkQuality and report the results in the menu bar every 20 minutes. You can download it here if you’re interested.
