I mean a slot defined by __slots__ = slot1, slot2, slot3, ..., without descriptors or specific __getattribute__ code on top of that. > - GetAttr: 46 seconds (46 seconds) > outside the loop: > PyObject *name = PyString_FromString("attr_one"); I think you should be using PyString_InternFromString, but it will probably still be slower than PyList_GET_ITEM, which is still much simpler. The next optimization is the one proposed by Carl, which should yield speed comparable to PyList_GET_ITEM.
