HTTP Intermediary Layer From Google Could Dramatically Speed Up the Web

grmoc writes "As part of the 'Let's make the web faster' initiative, we (a few engineers — including me! — at Google, and hopefully people all across the community soon!) 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 (essentially a shim between HTTP and the bits on the wire) for transporting content over the web, designed specifically for minimal latency. In addition to a rough specification for the protocol, we have hacked SPDY into the Google Chrome browser (because it's what we're familiar with) and a simple server testbed. Using these hacked up bits, we compared the performance of many of the top 25 and top 300 websites over both HTTP and SPDY, and have observed those pages load, on average, about twice as fast using SPDY. Thats not bad! We hope to engage the open source community to contribute ideas, feedback, code (we've open sourced the protocol, etc!), and test results."

Not a terribly new concept.

AOL actually does something similar to this with their TopSpeed technology, and it does work very, very well. It has introduced features like multiplexed persistent connections to the intermediary layer, sending down just object deltas since last visit (for if-modified-since requests), and applying gzip compression to uncompressed objects on the wire. It's one of the best technologies they've introduced. And, in full disclosure, I was proud to be a part of the team that made it all possible. It's too bad all of this is specific to the AOL software, so I'm glad a name like Google is trying to open up these kind of features to the general internet.
