This is a port of PyPy's method cache optimization.  It gives a very good speed-up to PyPy, and it is simple enough to be attempted on CPython.

The patch is against Python 2.4, which is the version I still use; I've applied the patch on the system-wide Pythons of a couple of machines a few days ago and haven't had any problem since.  It gives a consistent 20+% of speed-up on all applications and benchmarks I tried, and up to 36% in extreme OO examples like the "richards" benchmark.

The patch needs to be ported to the HEAD, and it needs some extra careful review.  I'm a bit too busy right now to do any of these but I'll eventually come back to it if nobody else does.
