the other server is 2x faster even without http/2

My wget implementation does not suppot http/2

HTTP Server:

  $ time wget https://1153288396.rsc.cdn77.org/http2/tiles_final/tile_18.png
  [...]
  real 1.038      user 0.038      sys 0.007       pcpu 5.37

HTTP2 Server:

  $ time wget https://1906714720.rsc.cdn77.org/http2/tiles_final/tile_18.png
  [...]
  real 0.539      user 0.045      sys 0.009       pcpu 10.01

of course that's just latency.. but this is hardly a scientific demonstration.

We should also consider the fact that this is cherry picking the worst trait of HTTP/1.1 and that's that it's latency sensitive.

A demo with a real webpage of large assets would be a better example.
