Do you have any real data to back it up? I'm not doubting it; I just want to see the real benchmark of an app in four modes:On the contrary, running a 64-bit application on a 32-bit kernel requires significant overhead on every transition from userland to kernel, and kernel to userland.
32 bit app on 32 bit kernel,
32 bit app on 64 bit kernel,
64 bit app on 34 bit kernel,
64 bit app on 64 bit kernel.
Well arstechnica or elsewhere would publish it sooner or later...
