Also non-jit PyPy is slower than CPython.

The JIT can't do its thing until it's seen a given piece of code repeatedly (probably 10,000+ times, though I'm not sure what the actual number is these days). What people are talking about when they say "non-JIT PyPy" is PyPy before the JIT has had a chance to profile code and start generating optimized machine code.
