My code is optimized to up to 10 positional arguments: with 0..10 arguments, the C stack is used to hold the array of PyObject*. For more arguments, an array is allocated in the heap memory. + /* 10 positional parameters or 5 (key, value) pairs for keyword parameters. + 40 bytes on 32-bit or 80 bytes on 64-bit. */ +# define _PyStack_SIZE 10 For keyword parameters, I don't know yet what is the best API (fatest API). Right now, I'm also using the same PyObject** array for positional and keyword arguments using "int nk", but maybe a dictionary is faster to combinary keyword arguments and to parse keyword arguments. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue26814> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
