Current State of Unladen Swallow (Towards a Faster Python). The Unladen Swallow team are now planning to merge their work back in to the mainline Python 3 branch, adding a powerful incentive for Python developers to port their old Python 2 code (since the official Python 2.x line is extremely unlikely to have Unladen Swallow merged in to it). # 7th January 2010, 12:41 pm


Apparently [unladen-swallow] is already 30% faster than CPython, and this version is being used to run some of the Python code on YouTube.

ProjectPlan—unladen-swallow. A branch of Python 2.6 aiming to radically improve performance (the target is a 5x improvement), by compiling Python to machine code using LLVM’s JIT engine. I think this is a Google 20% time project (or maybe not, see the comments). An early version without LLVM is already available for download. # 30th March 2009, 10:09 am
