This is an interesting demonstration of a use case HTTP was made for, and  
where HTTP works well. The issues we are facing are non-working pipelining  
in HTTP/1, increase in HTTP header size from things like cookies and  
ua-prof-diff, and streaming of video. It doesn't appear that you are  
testing these issues, so it makes sense that the performance difference  
isn't that great. It would be preferable if HTTP/2 would always win over  
HTTP/1 though.

Since your minify-tests performs non-reversible content modifications, I  
would be very careful to use those results.
