Does removing the PyLong_Check call in PyLong_AsSsize_t make any noticeable difference to these timings?
Making no other changes from the trunk, removing the PyLong_Check and NULL check from PyLong_AsSsize_t shaves off 4 nanoseconds (or around 4% since the trunk is around 100 nanoseconds).
Thanks. I'd call that a noticeable difference. I'd be +1 on changing this particular check to an assert and so disabling it in non-debug builds. I'd like to bet that the majority of calls to PyLong_AsSsize_t are internal. Mark
