This test 'cheats' in favor of HTTP 2.0. The problem is that there are ways around the HTTP 1.1 limitation of 'one connection, one thing,' and this test uses absolutely none of those ways. It makes a connection, receives an image, closes a connection, opens a connection, receives an image,... 200 times.

The HTTP/2 test does exactly what it's designed to do: opens a lot of connections and receives the images pretty much all at once.

This isn't to downplay HTTP/2, but it's something that should be noted for _this_ test.
