Description
I've observed a roughly 11% performance overhead when using the python distribution shipped with the python:3 image, compared to the python distribution installable through ppa:deadsnakes/ppa: https://stackoverflow.com/a/76133102/2808520

My guess is that the with debug_info compilation introduces this ~11% performance overhead.
I'd appreciate if someone could tell me if my guess is correct.
