Python multiprocess profiling

Question

I\'m struggling to figure out how to profile a simple multiprocess python script

import multiprocessing
import cProfile
import time
def worker(num):
    time.         


        

Answer 1

You're profiling the process startup, which is why you're only seeing what happens in p.start() as you say—and p.start() returns once the subprocess is kicked off. You need to profile inside the worker method, which will get called in the subprocesses.
