Is ... that faster than CPython? Wow. Maybe I should symlink /usr/bin/python -> pypy on my laptop....

It's much slower. On my machine, "$PYTHON -c ''" (execute nothing) takes 60ms on Python 2.7, 80ms on 3.6 and 250ms on pypy.

It's not. You can test it on your system. In every case I've seen, Python starts up faster than PyPy. Neither takes a super long time.

PyPy has some great performance characteristics, but startup time isn't one of them.
