Use the proper CFLAGS, OP. On my notebook.

$ time gcc -O3 -march=native -mtune=native -pipe -fomit-frame-pointer -funroll-loops -ffast-math -fforce-addr -msse -msse2 -msse3 -mmmx bench.c 



real    0m0.070s

user    0m0.052s

sys    0m0.020s



$ time ./a.out 



real    0m0.002s

user    0m0.000s

sys    0m0.000s



$ time echo "for i in range(100000000): b = 3.14159265 / 1.161803399" | python # crash incoming
