before: 15773 pystones, 29.9 mPB after: 12690 pystones, 31.4 mPB
What's the mPB number? If its the time to complete parrotbench, this is actually a slowdown, just as for pystone.
Switch back to CVS:
19531, 19379, 19531, 19379, 19305, 19084 pystones, 31.4 mPB
Switch back to Tim's patch:
15015, 15480, 14588 pystones
should not need, but: make clean && make (just make on previous, only listobject.c being recompiled)
Still patched: 13158, 14006, 13193; restart python; 15923, 16722, 16023 restart python; 12953, 13698, 12953, 13513
Well, pystones are all over the map on this box. But the improvement is there for punchit and the parrotbench benchmark is solid across the change.
Unclear. Please clarify mPB. --Guido van Rossum (home page: http://www.python.org/~guido/)
