The conditions are unfair: the C++ version uses double, whereas the Pharo version uses Integers. Change the C++ version to use int and then report the results :-).

So I was bored and decided to test how fast pharo is compared to C++.��

so I tested addition��

C++ version:

#include <stdio.h>

int main()

{

�� double x=0;

�� while(x<1000000000)

�� �� {

�� �� x = x+1;

�� �� }

�� return 1;

�� }

��time ./test1

�� �� �� �� 2.84 real �� �� �� �� 2.84 user �� �� �� �� 0.00 sys

Pharo version:

time ./pharo Ephestos.image eval "|x| x := 0. 1 to: 1000000000 do:[:each| x := x +1]"

1

�� �� �� �� 2.09 real �� �� �� �� 1.94 user �� �� �� �� 0.08 sys

Pharo is��+50% faster than C++ ... o_O ... that's suprising, I assume here Pharo VM probably does some kind of optimisation.��
