"As part of the Let's make the web faster initiative, we are experimenting with alternative protocols to help reduce the latency of web pages. One of these experiments is SPDY (pronounced "SPeeDY"), an application-layer protocol for transporting content over the web, designed specifically for minimal latency. In addition to a specification of the protocol, we have developed a SPDY-enabled Google Chrome browser and open-source web server. In lab tests, we have compared the performance of these applications over HTTP and SPDY, and have observed up to 64% reductions in page load times in SPDY." - SPDY: An experimental protocol for a faster web.
Google's idea for HTTP replacement. Interesting read. The bad things that we need replace not only servers but browsers also. If it is not Chrome :-)
