Primality test Python C extension is slower than pure Python

QUESTION

Primality test Python C extension is slower than pure Python

Asked 2022-Feb-21 at 14:28

I've implemented a 6k+-1 primality test function both in a C extension and pure Python code but seems pure Python code is much faster! is there something wrong with my C code or something else? I also compiled a similar test in pure C with the is_prime function, and its execution time was the same as the C extension (almost 2sec)

I think your C implementation is buggy regarding integer overflows and signedness and ends up in a bigger loop than the Python version.

Changing the parameter type to unsigned int (and i too, since otherwise that's a compiler warning):

Install PrimeModule

You can download it from GitHub.
PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
