Time to debunk this.
Equipment used to do the tests.
Internet 100Meg down 6Meg up
First test the result shows I have a higher upload speed than I am capped at. It repeats the same result but doesn’t go over 50Meg. If you look at the top left, I have the nPerf app that counts my traffic in Kbits or Mbits whenever I have activity. Sadly it didn’t go over 1Meg in these speedtests.
Ping on the browser is way higher than the app, so traffic is shaped somewhow.
These are the normal speedtests with the Ookla app, and Nperf does actually count the right bits being transferred
