Recent versions of IE have been very noticeably faster on my machines than Chrome. Every time I open IE up to test a site that I've been working on in Chrome, it's amazing how much smoother animations are and how much quicker pages render. Ironically, this difference between them is most readily apparent when using touch to scroll and zoom. I'm all for making performance a priority, but the IE team found a way to implement pointer events without sacrificing performance. Surely they aren't uniquely capable of this engineering feat. In the long run, shackling the web to the iPhone 1's touch input scheme seems awfully short sighted. I don't know if IE's pointer event model is the best alternative, but touchstart/down/up/stop definitely isn't.

IE is faster in some areas because it uses some very controversial tricks, like caching all AJAX requests for the entire session. So yeah, it might be faster, but you might also get outdated data.

  When I think about how IE is faster on my machines, I'm mainly thinking in terms of page rendering performance after the first byte and animation/scrolling smoothness. Lately, I've actually found myself lamenting that I needed to further optimize a couple sites so they'd run smoothly on Chrome and/or Safari, when they were already buttery smooth in IE. That's something I never thought I'd find myself thinking. (BTW, I see that someone downvoted you, but that wasn't me. Your point about AJAX caching is a good one.)

    I've heard that IE9+ has very effective GPU rendering. That could explain its rendering and animation/scrolling performance. The GPU compositor in Chrome & Safari is kinda hacked-in; it renders layers on the CPU first, blits them to the GPU as a texture, and then composits on a full-layer basis. Touch the CPU renderer and performance immediately goes to shit. I wouldn't be surprised if things get better, at least for Chrome, in the near future.
