	Google released Page Speed as open-source software for the Firefox browser. Page Speed evaluates web pages against web performance best practices and gives suggestions on how to improve them. Like YSlow, Page Speed uses the Firebug plug-in to analyze pages. Page Speed evaluates performance from the client point of view, typically measured as the page load time. It covers five categories of page load optimization Optimizing caching — keeping your application's data and logic off the network altogether Minimizing round-trip times — reducing the number of serial request-response cycles Minimizing request size — reducing upload size Minimizing payload size — reducing the size of responses, downloads, and cached pages Optimizing browser rendering — improving the browser's layout of a page To know more about Page speed Click here
