OK, so I think to get real information, you'll have to verify the exact time
to complete the copy.  I have whipped up a program to create a file, copy it,
and calculate how long it took.  On my development machine with a very fast
hard disk, it was about 10-12ms.  Don't have a Windows CE device with RAM
filesystem enabled to try, but give it a try yourself and let us know what
results you get (note that I didn't create a method to get the data, other
than the debugger, so you'll have to enhance it for CE a bit).

While you're at it, tell us some more information about this build:

Windows CE version?
DEBUG or RETAIL build?
if RETAIL build, is the BSP outputting RETAIL messages?
if DEBUG build, are you connected to Platform Builder for kernel debug,
RELFSD directory access?
