You’ve probably read the news when Internet Explorer 9 Preview 7 was released a while back. Internet Explorer is now the fastest browser in the world! Wow! While I am sure that those geeks who have a somewhat troubled relationship with Internet Explorer will find some benchmarks that show that IE9 is actually the slowest browser, it is worth having a look at the new features that make Internet Explorer perform so well.

Hardware acceleration

IE9 display uses the Graphics Processing Unit (GPU) to render all graphics and text. This reduces the load on the CPU and thus improves the overall performance while loading pages.

JavaScript-Engine Chakra

The new JavaScript Chakra engine makes use of multiple CPU cores to background compile JavaScript code. It can also use the computer’s CPU.

Modern processor instruction sets

Microsoft isn’t specific about this feature, but it seems it has something to do with Streaming SIMD Extensions 2 and 3 (SSE2, SSE2), which supposedly improve the gaming performance on Intel machines.

Add-on Performance Advisor

Often when a web browser becomes unstable and slow, it is not the browser itself but an add-on that is the culprit. The Add-on Performance Advisor helps you identify those malfunctioning add-ons. IE9 will display corresponding messages in the new notification area. You can also display the load times for each add-on and then get rid of those extensions that slow down Internet Explorer.
