I wrote both a lua version and a python version. Under
linux, lua is about 2-3x faster than python, and about
50% of a C implementation.
However, when I put the same code to run under

I have also tried to illiminate the file io(so

What would cause such a strange behaviour ?
Both lua(luajit) and the python code are compiled
