HTTP/2 - the IETF Is Phoning It In
An anonymous reader writes HTTP/2 is back in the spotlight again. After drawing significant ire over a proposal for officially sanctioned snooping, the IETF is drawing criticism for plowing ahead with its plans for HTTP/2 on an unrealistically short schedule and with an insufficiently clear charter. A few days ago the IETF announced Last Call for comments on the HTTP/2 protocol.
Poul-Henning Kamp writes, "Some will expect a major update to the world's most popular protocol to be a technical masterpiece and textbook example for future students of protocol design. Some will expect that a protocol designed during the Snowden revelations will improve their privacy. Others will more cynically suspect the opposite. There may be a general assumption of 'faster.' Many will probably also assume it is 'greener.' And some of us are jaded enough to see the "2.0" and mutter 'Uh-oh, Second Systems Syndrome.' The cheat sheet answers are: no, no, probably not, maybe, no and yes."
"Given this rather mediocre grade-sheet, you may be wondering why HTTP/2.0 is even being considered as a standard in the first place. The Answer is Politics. Google came up with the SPDY protocol, and since they have their own browser, they could play around as they choose to, optimizing the protocol for their particular needs. SPDY was a very good prototype which showed clearly that there was potential for improvement in a new version of the HTTP protocol. Kudos to Google for that. But SPDY also started to smell a lot like a 'walled garden'."
"The IETF, obviously fearing irrelevance, hastily 'discovered' that the HTTP/1.1 protocol needed an update, and tasked a working group with preparing it on an unrealistically short schedule. This ruled out any basis for the new HTTP/2.0 other than the SPDY protocol. With only the most hideous of SPDY's warts removed, and all other attempts at improvement rejected as 'not in scope,' 'too late,' or 'no consensus,' the IETF can now claim relevance and victory by conceding practically every principle ever held dear in return for the privilege of rubber-stamping Google's initiative."

A typical "modern" web site loads untold numbers of scripts and other files from dozens of domains, mostly for tracking, A/B testing and other things that the user doesn't want or need. That's what makes the web slow. I don't think HTTP is a particularly nice protocol, but HTTP/2 is taking a bad protocol and making it worse by "optimizing" it, while the real bottleneck is obviously somewhere else.
