Or more than one hardware architecture (which you didn't even say what
you tested...)
Also, I would like to see the actual test code. I wonder whether what
you measured is the ability of the compiler to optimize references to
successive elements of an array inside a loop; that has little or
nothing to do with the typical usage of BufferGetBlock().
