Cython string performance
WebCython is nearly 3x faster than Python in this case. When the maxsize variable is set to 1 million, the Cython code runs in 0.096 seconds while Python takes 0.293 seconds (Cython is also 3x faster). When working with 100 million, Cython takes 10.220 seconds compared to 37.173 with Python.

The first step to improving an application’s performance is to profile it—to generate a detailed report of where the time is being spent during execution. Python provides built-in mechanisms for generating code profiles. Cython not only hooks into those mechanisms but has profiling tools of its own.
