Why is there such a dramatic performance gap / slowdown for 3.10 + 3.11 compared to 3.9.12?

That's pypy 3.9.12, it has a JIT implementation to interpret python. The other two are standard CPython which doesn't JIT interpret the code.

Does pypy support numpy now?

yes

    $ pip install numpy
    <snip building wheel>
    $ python --version && python -c "import numpy; print(numpy.identity(5))"

That's 3.9.12 of PyPy, not CPython

Not OP, but are you taking into consideration that it is not Python 3.9, but pypy, which is distinct
