Getting faster load times often means downloading the page’s critical resources as early as possible. But sometimes the browser doesn’t know which resources to load until a fairly late stage in the page download. Wouldn’t it be great if we as web developers could help it out?
Well, we can! An old set of de-facto standards is being revived and improved as the Resource Hints and Preload standards. Together they give us the ability to clue the browser in on what’s going to happen in the current page’s navigation, and what’s likely to happen in the next one.
In this talk we’ll go over these standards and see what each of them does, when to use each one, and what are their benefits as well as possible costs.

He takes image bloat on the web as a personal insult, which is why he joined the Responsive Image community group and implemented the various responsive images features in Blink and WebKit.
