JavaScript, graphics performance improvements coming in IE9

Both the new JavaScript engine and the new graphics technoogy will improve the browser's performance. Microsoft made the point that different websites place different performance demands on a browser. Some are more scripting intensive, others more graphically intensive; some have complex layouts, others are simple. This has the consequence that to improve performance across the board demands a wide range of optimizations and improvements. With IE9, Redmond intends to not just improve performance in limited benchmarks (that focus on a single aspect of browser performance), but to ensure that real-world websites become faster.
