There are two classes of improvements that this talk will cover:
1. Server side changes, like SPDY and HTTP Origin/Hop Hints
2. Browser changes, like support for WebP, Client Hints, and pre-fetching.
The talk will go over each technology briefly, and cover the current state of support. Then I’m going to take a real world example of a typical site and show what the performance improvement would be if all of these technologies were leveraged to the maximum and supported fully by all browsers that visited the page. We’ll compare before and after views with WebPagetest, and put some bounds on the opportunity that we are missing out on because of delays in support for new standards.
Finally, the talk will close with a call to action – encouraging people to reach out to CDNs, standards bodies, and browser vendors to ask for support. The primary purpose of this talk is to raise awareness about these options and push the industry and the web forward by getting more people talking about and asking for adoption.
