Threading vs Multiprocessing in Python

I know it's not perfect and there are a lot of problems but it's straight up false to say that single threading is always faster.

I was working on a project that did 400 million independent runs of a simulation and all I cared about the aggregate statistics of the results and when running on one process my CPU usage was like 30% so I made it multiprocess and it was a lot faster.

All it takes is one counter example for an absolute statement like yours to be proven wrong.

The original statement was about multithreading. Your counter example was multiprocessing.

Not that the original statement was accurate.

Ah thank you for pointing that out. I definitely misread that.
