There is still a gap between IE 8 performance and IE 7 performance.

On June 23, March 20, when I spoke at MIX 09 today, Dean hamamovich, product manager of Microsoft IE 8, played a video showing how IE 8 loads and renders webpages with improved speed.

According to foreign media reports, tests show that IE 8 executes JavaScript code 238% faster than IE 7. If the performance of IE 7 is set to 1, the performance of IE 8 RC is 2.19, and that of IE 8 RTM is 2.36.

However, compared with other browsers, IE 8 still has a certain speed gap. For example, Firefox 3.0.7 executes JavaScript code twice faster than IE 8 RTM, while Windows version of Apple Safari 4 is 14.39 times faster than IE 7.
