You should identify which function is getting called most often. However, for most scripts cProfile provides information that is too fine grained. The following cProfile and profile provide deterministic profiling of This particularly applies to benchmarking Python code against C code: the profilers introduce overhead for Python code, but not for C-level functions, and so the C code would seem faster than any Python one.
