[pypy-dev] Pidigits performance without FFI

Hi folks I've been looking at the pidigits benchmark from the Computer Language Benchmarks, but measuring performance without FFI (so native Python numbers instead of GMP). You can see my results here: https://github.com/Wilfred/the_end_times#preliminary-results I'm seeing better performance for CPython than pypy3 on simple arithmetic code. Is this to be expected? Could I make pypy3 perform better? Wilfred
