Well, myh results are a little bit confusing again, if using
pre-increment, for shows up faster now. But while post-increment is
the fastest :) Is there any logic why we all have different results?
does it has to do something with the type of CPU, i'm using AMD
Athlon. 1800+ (clocked down from 133 to 100 * 11.5)

For pre-increment (100000): 0.026
For post-increment (100000): 0.030
While pre-increment (100000): 0.029
While post-increment (100001): 0.023

ps. @ Mario: Youre C2D got owned by a AMD 1.15Ghz :)
