   For a VAX, a PDP, or many other old processors, sure.  But that's
   just because the CPU under the emulator is orders of magnitude
   faster than the original hardware.

   Modern x86 don't tend to be orders of magnitude faster than Alpha or
   Itanium.

   And the time needed to run a particular CPU test on an emulator will
   always reveal that it is slower than running native code on the host
   CPU.

   As for disk speeds, same progress.
