I tried this test on mobile (iPhone 6 with iOS 9) over a flaky hotel wifi, and I got impressive results, 25s vs 3s: http://m.imgur.com/ND1wzZs http://m.imgur.co

  Yes – HTTP/2 will show the greatest impact on any connection with high latency because you avoid the classic HTTP 1 behaviour where each request must finish before the next one can be issued. If you have a low-latency connection close to the server you can easily find cases where HTTP/1 is still competitive – e.g. in this case using Akamai's demo with a 2ms ping time to their closest CDN node: https://www.dropbox.com/s/9zo844ue7ehwg58/Screenshot%202015-08-20%2015.04.30.png https://www.dropbox.com/s/9zo844ue7ehwg58/Screenshot%202015-... (That's presumably due to the HTTPS setup – even with caching disabled, that page takes ~.8 seconds on a reload) The catch, of course, is recognizing that this is not the case for most people and so even if we're personally not seeing a huge benefit on a fast computer in an office, it's still of huge benefit to anyone on a cellular network, flaky wifi, saturated ISP connection on another continent.
