By Rahul Bansal and Kishore Simbili, PageSpeed Teammake the web fasterPageSpeed Service

Make HTML cacheable. Typically, most web pages are not cached because they contain small amounts of personalized information or other non-cacheable data. This rewriter separates the non-cacheable portions from the HTML and enables caching for the rest of the content on PageSpeed servers. When the page is loaded, PageSpeed servers send the cacheable parts immediately while non-cacheable parts are fetched from the origin server & patched into the browser later.

Prioritize visible content rendering. Rendering of a modern web page requires several network resources, but not all of them are needed right away. This rewriter automatically determines and prioritizes the content that is above the fold of the browser, so that it doesn’t have to compete with the rest of the page.

Defer Javascript. JavaScript execution is deferred until page load so that it doesn’t block rendering of visible content.
