IE9 Platform Preview 7: performance is the priority

By Peter Bright

Just three weeks after the release of Platform Preview 6, Microsoft has released a seventh preview of Internet Explorer 9. The highlight of this new release is not new standards compliance but rather performance.

Improved performance has been a key goal of Internet Explorer 9's development. The new browser version relies heavily on GPU acceleration to provide high-speed graphics rendering and animation, and it includes a new JavaScript engine, codenamed Chakra, that compiles JavaScript in the background to achieve JavaScript performance that's tens or hundreds of times faster than Internet Explorer 8.

Throughout the development process, Microsoft has emphasized that the focus is on real-world website performance, not on popular but narrow benchmarks like the SunSpider JavaScript benchmark. Internet Explorer 9's SunSpider performance has improved over the course of its development, but the company says that this has been a side-effect of its real-world focused improvements rather than a deliberate objective.
