" summary

Average page load time is 4.9 seconds for a 320 KB page on a 1.8 Mbps line while many sites make 44 resource requests and perform seven DNS lookups, so the goal is to reach ~100 ms by fixing software not bandwidth. Practical wins include browser engine speedups (Chrome/V8), TCP tuning that yields 12% improvement, SPDY-like HTTP changes giving 25% faster loads and 40% fewer packets, header compression cutting headers by 88%, Android SSL ~10% faster, plus Google Public DNS 8.8.8.8 and dev tools like Closure and BrowserScope.
