WebBTW most of the overhead that comes with CFFI is removed by the JIT under PyPy which on CPython remains so the calls have to be faster on PyPy compared to CPython. If you find cases where the JIT is warmed up and the code is still slower it is code outside of CFFI that is causing the slowdown. While the author indicated that they had a "warm ... WebGoals¶. The interface is based on LuaJIT’s FFI, and follows a few principles:. The goal is to call C code from Python without learning a 3rd language: existing alternatives require users to learn domain specific language (Cython, SWIG) or API ().The CFFI design requires users to know only C and Python, minimizing the extra bits of API that need to be learned. binding arbitration def

WebPybind is derived from boost::python, so it's not much different. I wrote a large Python binding in the past for a moving C++ library target, using boost::python, and keeping the C++ binding code up to date was a nightmare akin to maintaining a fork of any fast-moving project.
