I wonder how much JIT compilation would help, without any hand-optimization? e.g. it'd do the initial inlining. I've been amazed at Java's speedup over multiple runs: dead-slow on startup, then improving rapidly over the next 10-20 runs, and even keeps improving slowly after that. It's a bit magical. Much (all?) of that JIT tech should be applicable to Python, I'd think. BTW: link is to the comments, not the story
