I can't see how this is possible.  I can see how recompiling stuff for
32-bit *might* make it up to twice as fast, but not 4 times as fast. Please
justify this.  I, myself, have ported DFLAT (the text mode user
interface lib from Dr. Dobb's Journal) and it's sample application,
to 32-bit extended dos and have noticed no speed increase at all.
And this code is full of far pointers.  I have seen some small, tight
programs (gif decoder code) that does not benefit at all from
32-bit.  The pointers are all near and the words used are all 16bit, and
there is no reason to make them 32-bit.  From my experience, the 
advantages of having 32 bits are more in the form of having a large
flat address space, and much less in the form of more speed.
