Correction: I get a 11% speed boost with the -O3 flag:

0: 60387275.67636769 allocations / second
1: 63133704.55951615 allocations / second
2: 169169529.8609596 allocations / second
3: 188535531.4062488 allocations / second
1 / 0: 104.5480258090584% boost
2 / 1: 111.447688931456% boost

So I am not sure if this is worth the trouble.
