You should read up on WOW64. It's not emulation. The 32-bit code is passed to the (native) 32-bit processor at machine speed.
The slowness is probably related to either changes in the architecture that the apps do not take into consideration, or any kind of lingering debug or test code.
The hard drive ratings in Win7 have been reporting abnormally slow for a while. I haven't read up on why this is, or if the benches are accurate.
