Changing to better test suites isn't the answer, I know I've tried a lot to
educate and push for bespoke test sites for our customers .
This is all about happy illusions on the user side.
This is a branding and markets problem. In NZ, 'the' site for reference
that users go to is speedtest. Because of that RSPs deploy more speedtest
servers on their networks and you end up with a vicious cycle. Get enough
user driven complaints and you end up having a user driven push to make
your network 'look good' by doing otherwise silly things.
So if ookla implemented a udp based test, changed it's statical weighting
and data mining methods overnight. At least in NZ that might help.
For the RSPs it is always going to be easier to modify a buffer or queue
somewhere. And that is going to make their project managers and
stakeholders happier straight away.
