Test results
HTTP/2 demonstrated to be consistently faster then HTTP/1.1 on this test
- 4 times faster on WiFi / 20Mbps cable, average server ping 50ms
- 6 times faster on LTE network, average server ping 90ms
- 15 times faster on 3G network, average server ping 120ms
- 2 times faster on 2G network, average server ping 400ms
The reason HTTP/2 is just 2x faster on 2G network is due to EDGE bandwidth constraints as at 170Kbps link rapidly saturates.
