To obtain 200-250% in speed gain won't be possible for this GCC

To understand the law's idea, to see first the red-A & blue-B graphic.
GCC throws more time optimizing than analyzing lexically unless it
deactivates the optimizing option -O.
I redacted a new "Speedup in a sequential program" in
http://en.wikipedia.org/wiki/Amdahl%27s_law with a numerical example
for more clarification of the idea of usefulness of the Amdahl's Law.
To see if you are understood better it than before, little stupid!
