Microsoft on Wednesday released the seventh platform preview of its upcoming web browser Internet Explorer 9 (
). Comparatively less stable than beta builds, platform previews are aimed at acquainting developers with new features and gathering valuable feedback.
According to Dean Hachamovitch, Microsoft’s corporate vice president of Internet Explorer, who wrote a copious blog post to discuss the latest platform preview release, improving real world site performance, and not “subsystem microbenchmarks,” remains the real focus of company’s development efforts.
But he soon clarified: “We’ve been consistent in our point of view that these tests are at best not very useful, and at worst misleading. Even with the most recent results in the chart above, our motivations and our point of view remain unchanged.”
“We’ve focused on improving real world site performance. We’ve made progress on some microbenchmarks as a side effect. Focusing on another subsystem microbenchmark is not very useful.”
