How to profile long running application ?

[eromoe]

Hello,

I have a project need multiprocessing and would take over 4 hour in a 36cores vps .
My local machine is windows, has some problem to run mprof .

So I run vprof -c cmh "run.py salecount -n 1" --output-file profile.json on a remote vps .
Because vprof didn't support multiprocessing , I can't wait it done .
Abort from execution, it didn't export any files .

What is the correct way in my case ??

I would suggest running your program on smaller input if it's possible.

You don't need to run your full application. Comment out code and tweak the main loop so it runs the program directly instead of multiprocessing, and runs on say a quarter of the data you're using. You're looking for the functions taking high proportions of time, not the exact full runtime.
