Just to clarify, if I understand you correctly, you mean that by investing some serious effort into optimising those "small" inefficiencies one could improve the situation from 5x to 3x. However, I wonder if anything could be done on the SIMD front in a rather generic way with a reasonable investment of time but without going the full NumPyPy way, e.g. by doing something special for tight loops performing math on objects with a special layout (lists, arrays)... -- Sincerely yours, Yury V.
