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 :-). Michal On 17.12.2016 13:16, Dimitris Chloupis wrote:
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.
