* Replace PyObject_CallFunctionObjArgs() with fastcallVictor Stinner2016-12-011-3/+3
| | | | | | | | | | | | | | * PyObject_CallFunctionObjArgs(func, NULL) => _PyObject_CallNoArg(func) * PyObject_CallFunctionObjArgs(func, arg, NULL) => _PyObject_CallArg1(func, arg) PyObject_CallFunctionObjArgs() allocates 40 bytes on the C stack and requires extra work to "parse" C arguments to build a C array of PyObject*. _PyObject_CallNoArg() and _PyObject_CallArg1() are simpler and don't allocate memory on the C stack. This change is part of the fastcall project. The change on listsort() is related to the issue #23507.

| | | | | | | | | | | | While no copyright violation occurred, the license which 'Numerical Recipes' operates under is not amenable to Python, so to prevent confusion it's easier to simply remove its mention.

* Issue #8692: Improve performance of math.factorial:Mark Dickinson2010-05-151-20/+240
| | | | | | | | | | | | | (1) use a different algorithm that roughly halves the total number of multiplications required and results in more balanced multiplications (2) use a lookup table for small arguments (3) fast accumulation of products in C integer arithmetic rather than PyLong arithmetic when possible. Typical speedup, from unscientific testing on a 64-bit laptop, is 4.5x to 6.5x for arguments in the range 100 - 10000. Patch by Daniel Stutzbach; extensive reviews by Alexander Belopolsky.
