Summary: Internet Explorer 9 (IE 9) is not as fast as Microsoft wishes people to believe, according to independent tests

MICROSOFT loves to compare competitors' real products to products that it has not even released yet (and therefore cannot be benchmarked reliably). Microsoft uses draconian terms in the EULA to prevent parties from conducting and publishing benchmarks. False performance claims are currently being spread around by Microsoft, touting the speed of a product which is not even out in the market.

Ryan Farmer has performed some tests and he concludes that "IE 9 Preview 3 is still really slow…"

That was the answer to your question. “Is it really fair to be bagging on something that’s not even released?”. Yes and no. Normally no, but when Microsoft is already lying about it being faster than the speed of light on a day that God did a line of coke, I’d say they made the damned thing fair game already.

In one of our IRC channels, Ryan said that "IE 9 is as fast as a browser can get without breaking the laws of physics. Lie mode cancel. How does Microsoft manage to make up benchmarks that anyone can download their browser and debunk?"

"There are ways to cheat," Oiaohm responded to him. LifeHacker has its own benchmarks too. Microsoft is not a winner there, either. ⬆
