This is a script that calculates how much time it takes to run a function consisting of N NOP bytecode operations (these have no effect and are usually removed as part of the peephole optimization step), as a function of N.
To use this, run pip install noop_timer. For convenience, it is probably best to use a virtual environment:
python -m virtualenv noop_venv --python=3.7
source noop_venv/bin/activate
pip install noop_timer
To run, execute the module with python -m noop_timer.
