Google today 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 runs on Mac OSX, Windows, and Linux for the Firefox browser. The interface has some similarities with YSlow, and allows recording of activity and more detailed waterfall graphs. You can inspect HTML, CSS, and the DOM to drill down into the web page code (see Figure 1).
