An anonymous reader writes: Firefox 7 was released a couple days ago, and now the latest Web browser perfromance numbers are in. This article is the same series that ran benchmarks on Mac OS X Lion last month. This time around the new Mozilla release is going against Chrome 14 and Opera 11.51 in 40+ different tests on Windows 7. Testing comes from every category of Web browsing perfromance I can think of: startup time, page load time, JS, CSS, DOM, HTML5, Flash, hardware acceleration, WebGL, Java, Silverlight, reliable page loads, memory usage/management, and standards confromance. The article also has a little feature on the Futuremark Peacekeeper browser benchmark. An open beta of the next revision has just been made public. This new version adds HTML5, video codecs, and WebGL tests to the benchmark. It's also designed to run on any browser/OS/device combination — e.g. Windows desktop, iPad, Droid 2, MacBook, Linux flavors, etc. Another great read, a must for Web browser fanatics!
