Microsoft releases ie9 preview version

At today's mix 2010 Conference, ie9 released the Platform Preview (ie9 Platform Preview ),Official download:Http://ie.microsoft.com/testdrive/ (the download link is in the upper right corner of the page ).

 

 

 

This preview shows several features of ie9:

 

1. Speed

Ie9 will use the completely rewritten JavaScript Engine, codenamed "Chakra ". This new engine significantly improves performance. It is the result of sunspider testing. There is still much room for improvement in Chakra. I believe that in the future beta and official versions, the JS performance of ie9 will be refreshing.

 

 

 

 

2. GPU hardware-accelerated web page rendering

With GPU hardware acceleration, the rendering speed of ie9 is significantly higher than that of IE8. IE8 and other browsers currently use GDI rendering at a speed of about 10 to 10 per second ~ 16 frames. Ie9 can reach 60 ~ The rendering speed of 70 frames per second is equivalent to the rendering speed of 3D game animation.

 

 

3.Added support for HTML5, SVG, css3, and Dom.

Ie9 supports HTML5, css3, Dom, and SVG. SVG is W3C defined Web vector graphics/Animation Description Language, very powerful, can make extraordinary Web Animation, you can find svg in the http://ie.microsoft.com/testdrive/ demo program. SVG is a key feature of ie9. It is believed that it will have a profound impact on future web development, especially Web Animation/web games. It is recommended that web developers start to study SVG.
