The test program is a simple loop that mainly does a REAL multiplikation:

It would be interesting to see how the ratio changes when the loop would contain more floating point operations.
There is quite some overhead for the loop itself and having only a single multiplication inside the loop can be misleading to judge the performance of the FPUs.
Maybe something with a few trig functions and squares and exponentiation.

Another interesting detail for comparison would be the file size.

It may also be that the "compiler" just adds a wrapper around the tokenized BASIC program to make it run standalone (without LOAD and RUN). Then a speed gain would be very small if at all. Early Visual Basic Versions (1.0, 2.0) did this before later versions introduced compilation to machine code.
