SPDY, a protocol Google revealed in late 2009, dramatically speeds up Web page loading by changing the way that browsers communicate with servers. Until now, Google has only tested the research project internally and deployed it on a few of its own sites. But today, the protocol launches as a commercial product.
Website optimization company Strangeloop has built SPDY into its flagship product Site Optimizer, software that sits in between a website and its users, and adjusts the site’s code to make pages load more quickly. Strangeloop’s customers will have the ability to turn the protocol on easily; in tests, the protocol has sped up websites by 10 to 20 percent.
