Re: [pypy-dev] Pidigits performance without FFI

pidigits is based on long numbers. We can make pypy be the same speed as cpython (porting missing optimizations), but not faster, or at least unlikely. Since the time is spent in runtime, the JIT does not help at all. We tried to used GMP, but we found out that GMP semantics are not really suitabl

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
