6% faster on a template system simply by optimizing conditional jumps is quite neat. (the spitfire homepage itself is rather intriguing, they claim to be faster than plain string joining...) > I was mostly curious whether the POP_OR_JUMP and JUMP_OR_POP opcodes > had a noticeable performance impact, ie, do they make things fast > enough to warrant their inclusion over the old JUMP_IF_FALSE > implementations. Well, I don't remember really, although this is only a few weeks old. POP_OR_JUMP / JUMP_OR_POP will be used when the "and" and "or" keywords are involved. That's basically the only situation where you don't want to pop the top of stack after a conditional jump. _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue4715> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
