    It’s very misrepresentative that the red bar is less than a fifth the size of the blue bar on Total, when 87 is more than half of 133.

    Nice benchmark!!

    There is a 64 bit flash?
    Why wasn’t I informed?
    Is it possible to test other 64 bit browser?
    32 apps need to die.

  4. Ken Leese says:

    Unfortunately there’s no EASY way to make X64 the default IE browser. (Invocation from other programs etc…)

  5. Just tested the SunSpider benchmark under IE9 Beta and the result is unfortunately opposite, 32-bit IE noticeable by a factor of 3 faster than IE x64. Seems that the IE team did not optimize for x64.

    Yes, Sunspider will soon end up on 0MS like SSD drives, and heaven will open can’t wait…

    I cannot access my emails in Sky using the 64bit version??? Have switched back to version 8 and no touble at all so for me IE9 is rubbish, sorry.

      Did you turn on the Compatibility view mode to test? Some sites are broken using the default mode.
