This comparison is so completely wrong, as you guys have said. This is a comparison of page load time differences between the different devices, not a comparison of their respective CPUs. I'm pretty sure that iPhoneOS is quite a bit(/lot) better optimized for the hardware that's used in the iPhone and iPad compared to Android. AFAIK, Android does not make use of all the features present in the Scorpion CPU used in Qualcomm's Snapdragon platform (the same goes for the Cortex-A8 used in the Droid). Android does not make use of Scorpion/Cortex's NEON instructions for example.
These extensions will eventually be supported by Android, but Android will always be at a disadvantage compared to iPhoneOS in this regard. Android has to support a much broader range of hardware compared to iPhoneOS, which simply makes it hard to optimize for specific hardware features. This will improve over time, but in this case you can clearly see iPhoneOS making better use of the available hardware.
