Hi Christoph,
Is there a means of running the RPM test on an iOS 15 beta 2 (public beta) on an iPad Pro? It’s the only device I can spare to run the beta on, and I’m not on the Apple Developer program (I was for decades, but then went into the networking world ;) )
Like Rich, I’ve spotted inconsistencies from run to run, even on a line with just the router and my laptop connected. Is there a means of increasing the test runtime?
Rich, I like the ideas.
Regards,
Jonathan Foulkes

(Prior "art" - my coffee-shop-bloat-test.sh at https://github.com/richb-hanover/coffee-shop-bloat-test.) Here's the checkNetworkQuality.sh script:

Feature Requests: From this experience, I would like to see /usr/bin/networkQuality enhanced to (always?) display the date/time of the run, and to include an optional parameter for a test name/information. These parameters should also be included as new properties of the "-c" output. In addition, it might be good to include the build number in the output
