Read OriginalA PyPy developer recounts efforts to improve PyPy's performance on the Computer Language Shootout benchmarks. The article details how existing Python benchmarks were micro-optimized for CPython, harming PyPy. It describes rewriting the 'reverse-complement' benchmark for PyPy, encountering a CPython bug, and devising a clever workaround using ctypes to call libc's write() for better performance across both implementations.
