Microsoft today demonstrated an early, three week old, build of Internet Explorer 9 at Microsoft’s Professional Developers Conference 2009.

IE 9 will take advantage of the power of the GPU for all page rendering and developers can exploit this using CSS, DHTML and javascript. In just three weeks Microsoft believes performance has increased for IE9 resulting in smoother rendering and improved performance. Interoperability and standards support is increasing and features such as rounded corner CSS support will be built in. A new JS engine will also be built into Internet Explorer 9.

Microsoft offered no time lines or indications as to when a build of Internet Explorer 9 will be available publicly. Steven Sinofsky, President, Windows and Windows Live Division, mentioned that Microsoft had only begun working on Internet Explorer 9 three weeks ago, according to our sources the latest internal build is labelled 7658.0.091116-1745.

Microsoft’s Channel 9 team have posted three demo videos, check them out below.

The results are in from benchmarks of Firefox 3.5, performed by ZDNet.

The benchmarks test all the main browsers from Google Chrome 2.0.172.33, Safari 4, Firefox 3.5, Firefox 3.0.5, Opera 10 Alpha and Internet Explorer 8. Each browser was put through three tests including SunSpider javascript benchmark, V8 Benchmark Suite and finally the ACID 3 test.

Firefox 3.5 was built for speed and performance, compared to previous versions of Firefox. Firefox 3.5 performed better than Firefox 3.0.5 and Internet Explorer 8 in all three categories.

From the graphs, it is clear to see that Google Chrome performed the best overall, followed shortly by Safari 4 and then Firefox 3.5. Firefox 3.5 scored a 93 on the ACID 3 test, falling shortly behind Google Chrome, Safari and Opera 10 alpha, all scoring a perfect 100.

Firefox 3.5 is fast and speedy, but it’s still lacking the speed of Google Chrome or Safari 4 in terms of performance benchmarks.
