Good news for all of us who havent upgraded to IE8 yet. Internet Explored 9 is on its way! The web browser would be coming with great performance upgrades.
Browser performance involves many different sub-systems within the browser. Different sites – and different activities within the same site – place different loads and demands on the browser.
Developers want more capabilities in the browser to build great apps and experiences; they want them to work in an interoperable way so they don’t have to re-write and re-test their sites again and again. The standards process offers a good means to that end.
As engineers, when we want to assess progress, we develop a test suite that exercises the breadth and depth of functionality. With IE8, we delivered a highly-interoperable implementation of CSS 2.1 and contributed over 7,200 tests to the W3C. Standards that do not include validation tests are much more difficult to implement consistently, and more difficult for site developers to rely on.
Some standards tests – like Acid3 – have become widely used as shorthand for standards compliance, even with some shortcomings. Acid3 tests about 100 aspects of different technologies (many still in the “working draft” stage of standardization), including many edge cases and error conditions.
