It would have been nice to have timed this on ARM chips or 32-bit builds. I suspect that the previous code was mainly beneficial in register starved environments when it would have saved some memory accesses whenever there were an immediate first hit on a dictionary lookup (which is common). Also, it is more likely to make a difference on larger dicts where the memory accesses aren't all in L1 cache. |
