Надо замерить разницу в производительности, возможно, для python2 она не
такая как для python3. Вообще, когда разница в один регистр так сильно
влияет на результат, это свидетельство плохой оптимизации в реализациях
python. Обычные программы на C тоже дают разницу, и для некоторых
программ, таких как bzip2 и xz, ее несложно замерить, но она обычно
меньше 5%.
