Improving the performance of SPDY for mobile devices

SPDY [2] is an application layer protocol developed for reducing web latency. It is estimated that about 3.6 % of all websites use SPDY today [3], but that statistics hides how many web transactions use SPDY. It has rapidly gained adoption across Google, Facebook, Twitter, Yahoo, Reddit, and WordPress. While only a small fraction of all web-sites use SPDY today, SPDY-capable proxies are being de-ployed to provide the benefits of SPDY over the “last mile” while traffic between proxies and the origin webserver re-mains HTTP1.x for the time-being. SPDY improves web performance through various mecha-nisms including multiplexing multiple HTTP transfers over a single connection, header compression, HTTP request pri-oritization, and server push; which sends down content be-fore it is requested. Push can help when the client is under
