harmful than router prioritization

Free Press and other strict Net Neutrality advocates have their facts
backwards. The router prioritization that they claim is harmful to others is
actually not harmful and the CDN "geographic prioritization" that they claim
is harmless is actually the most harmful.

 

"Since both the YouTube and DigitalSociety server can run faster than my
broadband connection and I verified that each server can max out my
broadband connection, I can try to download a file from both servers
concurrently and compare how each server performs.  To my astonishment, the
YouTube server that is 47 ms away averages 2.3 times faster than our
DigitalSociety server which is 105 ms away!  It probably isn't a coincident
that 105 ms turns out to be 2.23 times slower than 47 ms so it would seem
that the Internet's congestion control mechanism (Jacobson's algorithm)
disfavors content proportionally to the latency.  Had the latency difference
been a 5-fold difference (which is often the case since I'm usually only 20
ms away from Google), a reasonable hypothesis (which I will test and update
when I get a chance) would be that Google's server would run roughly 5 times
faster than the distant server."
