To extend what you said a bit: PyPy is not only slow with extensions, it's also massively slower for running short-lived code that isn't repeated much, which is precisely the scenario of many if not most command line tools written in Python. Although I'm not sure there are enough people concerned about Python's performance in this scenario. And yeah, I would be happy to pitch in too if CPython can be 50% faster reliably. It only takes 500 people each pitching in $100 to reach $50k. Edit: somehow got $50k etched in mind when it says $500k. That’s more difficult from individual funding.
