Google has provided an update to the PageSpeed Insights Chrome extension it introduced last year. PageSpeed 2.0 is a major revamp, the extension has been rewritten and, while it does pretty much the same thing, it's gotten several new features and capabilities.One of big changes in the updated extension, now available in the Chrome Web Store, is that it's based on Native Client so it can run code that not only suggests things you can do to speed up your site, but also does some of the optimizations for you.
It also integrates tightly with the web developer tools already built into Google Chrome, so you'll know where to find it and how it works.
"PageSpeed Insights analyzes all aspects of a web page load and points out the specific things you can do to make your page faster," Google explained.
PageSpeed Insights, formerly Page Speed is designed, as the name clearly suggests, to test loading speed and provide info on what components drag out the most and what could be done optimization-wise.
Google offers the technology in a number of ways, there's an website version, a Firefox one, and even an SDK and an API.
