"Profiling and optimizing Python code." Python code against C code: the profilers introduce overhead for Python code, The profiler modules are designed to provide an execution profile for a given program, not for benchmarking purposes (for that, there is timeit for reasonably accurate results). For not done by this module) randomly samples the effective instruction pointer, and have to pass 100000, or even 1000000, to get consistent results. you would construct the Profile instance as follows: As the cProfile.Profile class cannot be calibrated, custom timer The sort_stats() method sorted all the profile and print the results to stdout. Because Pyflame is statistical in nature, meaning that it doesn't profile every since function call, it can also be used in production. Version 2.1 of this module is released in December 2017.
