Steady competitions among browsers is apparently visible.Latest versions of browsers are constantly released to make improvements in comparison to the previous ones, along side to evolve as the best among the competitors.The latest addition to this is Internet Explorer 9 by Microsoft.

Try downloading the IE9 Platform Preview and you can find that it doesn't replace your existing version of IE. Instead, it just runs in parallel to it.Internet Explorer 9 as of yet cannot be set as your default browser. It runs only in Windows Server 2008 R2, Windows Vista Service Pack 2 or Windows 7. As conveyed by Mircosoft, IE 9 will not run on Windows XP, now, or when it finally ships.

We just tried to download IE9 and since our Operating System is Windows XP we got the following error message while try to install it “Windows Internet Explorer Platform Preview does not support any operating System earlier than Windows Vista SP2.”

IE8 and previous versions of IE have been known for being much slower than competing browsers such as Firefox and Chrome.However the Internet Explorer 9 Platform Preview fixes this issue.A new JavaScript Compiler has been incorporated that speeds up scripts without by passing them on to the second core on dual core PCs .The performance is by now appreciably better than IE8, showing results on the Sunspider JavaScript benchmark that is around 5 times faster than IE8 . (Sunspider is one test to gauge a browser's JavaScript execution performance). It's also distant closer to the JavaScript speed of the pre-release versions of Firefox, Chrome and WebKit.

IE9 will also get a huge speedup from changing the Trident rendering engine from running on the presently GDI to hardware-accelerated DirectX. IE9 is the first browser to utilize DirectX, though Safari on Mac use Quartz rendering.This should perk up the appearance of fonts and performance of text animation without requiring modifications to the sites themselves.
