Back on performances: if you combined tp_fastcall-2.patch + 3 minor changes to use METH_FASTCALL, the bm_telco benchmark becomes 22% faster, which is significant for a benchmark: http://bugs.python.org/issue29301#msg285665 "20.9 ms +- 0.5 ms => 16.4 ms +- 0.5 ms" It also means that 22% of the benchmark time is currently spent in handling function arguments! I expected that most of the time would be spent on maths and I/O!
