The SPDY protocol can help provide much faster access to mobile Web sites, according to Google engineers.
In a test involving 77 Web pages across 31 domains, the team used the experimental protocol and a Samsung Galaxy Nexus phone running the SPDY-enabled mobile browser Chrome for Android. "The net result is that using SPDY results in a mean page load time improvement of 23 percent across these sites, compared to HTTP," say Google's Matt Welsh, Ben Greenstein, and Michael Piatek.
SPDY, first published in draft form in November 2009, is designed to transport Web content more efficiently by compressing HTTP headers. The protocol is not a replacement for HTTP, but it does override the HTTP connection management and data transfer formats. Google has deployed SPDY in a stable version of its Chrome browser and uses it for search and Gmail.
Other companies have started to adopt the protocol, and an Internet Engineering Task Force working group is considering including SPDY in the forthcoming revision of the HTTP protocol. Web site operators "should consider using SPDY to speed up access to their sites from mobile devices," say Welsh, Greenstein, and Piatek.
