About 10% of the improvement is due to the removal of SETLINENO opcodes; to remove this effect, you should compare python2.2 -O to python2.3.

But the rest is still impressive; I can't remember what we did...

Pymalloc? New-style object construction speedups? Faster getitem and setitem paths? These are just a few things that made speed differences in our app. I'm not familiar enough with pystone to know if (or which) of these are the lucky winners...
