Chakra is a JavaScript engine developed by Microsoft for their upcoming Internet Explorer 9 (IE). A distinctive feature of the engine is that it compiles JavaScript on a separate CPU core, parallel to the browser.[1] The engine will also be able to access the computer's graphics card processor (GPU), in particular for 3D graphics and video.[2] Microsoft's development of the engine was in direct response to the increasingly faster competing browsers, on which Internet Explorer 8 was lagging behind particularly in terms of JavaScript processing speed.[3]SunSpider tests performed on March 15 2010 have shown the then-available preview version of IE9 (using the then-current version of Chakra) to be quicker than Firefox (with SpiderMonkey), but slower than respectively Safari (with SquirrelFish Extreme), Chrome (with V8), and Opera (with Carakan). Microsoft itself published these results,[4] and downplayed its significance, pointing out that other elements, such as rendering and marshalling, are just as important for the browser's overal performance.[5]
