Dean Hachamovitch: IE9 - Questions and Answers
Not too long ago, a thread in the Coffeehouse was posted asking for your IE9 questions for Dean Hachamovitch, VP of Engineering for Internet Explorer. Thank you for asking such great questions, Niners! We didn't have time cover all of them, but we did manage to get through several of them (and there was some redundancy, too, so I took the liberty of choosing the questions. Also, I didn't ask any of the snarkier questions (though I probably could have, since Dean can handle it) and Dean did not want to see the questions before they were asked (which is commonplace among many executives). He's OldSchool9 that way and that's great!).
IE9 PP7 was released today and inside of it is one of the world's fastest JS engines (according to the SunSpider suite of JS performance tests, IE9 PP7 is faster than all other browsers out there...). Chakra, the IE9 JS engine, continues to evolve! Hats off to the Chakra team. Interestingly, Dean isn't overly excited about this news (though, obviously, he's thrilled) since JS execution speed is but one part of the overall performance story, which is actually divided into several pieces, not just two or three (see Jason Weber's quick chat on the overall performance characteristics that combine to form a user's experience of blazing fast web surfing, and read the IE team's blog post on the subject).
Here are the unedited questions Dean answered in this morning's conversation in the IE engineering building. Thank you, Dean, for taking the time out of your busy schedule to engage Niners' questions and concerns in an honest and open way. There is bonus footage at the end, too
I recommend watching all of this as the flow is nice and the questions lead into one another nicely. Great job, Niners! This is a 51 minute interview, which is a long time in VP Time. Dean's a big fan of yours, Niners.

I do recommend that you watch/listen to the entire conversation as it flows naturally from question to question with many questions and answers nicely building on those that come before and after...]
How you do personally feel about the way the HTML 5 standard is progressing? It's talking such a long time to form, it's slowing down the evolution of the uniform internet and causing more and more fragmentation between browsers. Is it not?
How do you measure Internet Explorer stability and when it's ready for RTM? Does the beta have any kind of telemetry for latencies: when the GUI freezes, when a page takes a long time to load, etc.
How many test cases do you have for IE9 at this point?
