IE 9 Performance Pipeline Overview

23 minutes, 31 seconds


Right click “Save as…”

Get your hands on the IE9 developer platform preview!

IE Performance PM Jason Weber and Performance Dev Lead Venkat Kudallur take us through the updated and improved performance pipeline in IE (hardware accelerated graphics rendering, new JavaScript engine (employing a dual execution pipeline), improved downloader, etc). We also get to see some really cool demos!

  • We need you to take us deep inside the JS engine.

    That's coming in the upcoming weeks. I'm on it.

    Hey Charles, amm when you get a chance.. can you ask them about what they are planning about the performance of UI? Smiley


    I understand performance of javascript and rendering is important, but all these things are already good enough for me in IE8. What I /really/ want is new tabs popping up instantly (now you have to wait one second or more just so that tab shows in the tab bar), IE not half-freezing if internet connection becomes a bit slower and similar.

  • CharlesCharles Welcome Change

    Will do. Good question!


    To be clear, these conversations are focused on the platform preview bits you now have in your hands - remember that this is not IE 9 the application, but rather an early look at the IE9 dev platform. I know you understand this. I want to reiterate it anyway. Smiley


  • It is showing media faliure when I start to play the video.Mad

    We are having some network-related issues. We are actively fixing the problem. Please check back after 8PM PST. Sorry for the inconvenience!

    Charles, the quality of these IE9 videos is amazing, especially the camera work and the quality of the encoding.  

  • CharlesCharles Welcome Change

    Thanks. The camera work and production magic is the work of Michael O'Neill, our resident film pro. We will be doing a lot more work together. He's got mad skillz.


  • Do we get one of those large displays with IE9? Smiley Seriously that's a beautiful monitor. What model is it? Must say the IE9 rendering / performance was nothing short of stunning.

  • One factor, though, is IE9's release schedule. Microsoft reps were completely noncommittal about when the browser would be released, in either a beta or final version. Given the frequency with which we see new editions of Firefox and Google Chrome, it's conceivable that another browser could come out with hardware acceleration before anyone gets a chance to use IE9.
