Since Microsoft made available to testers the Internet Explorer 9 developer preview in mid-March, there’ve been about 700,000 downloads of it, according to a source close to the situation, who asked not to be identified. The first preview was released in U.S. English only, Hachamovitch noted. The top five biggest downloaders (by country) were the U.S., Brazil, India, the U.K. and Germany (in descending order), he said. The majority 50% of testers are hammering on the preview’s speed and performance benchmarks, Hachamovitch said. Another 27% have been focusing on the Microsoft-provided graphics-centric tests, he said, while 22% have been putting the HTML 5 capabilities of preview through its paces.
Also, In this post, “we take a closer look at how hardware acceleration improves the performance of the Flying Images sample on the IE9 test drive site. When you run Flying Images across different browsers you’ll see that Internet Explorer 9 can handle hundreds of images at full speed while other browsers, including Internet Explorer 8, quickly come to a crawl,” notes IE team.
