Profiling

Speed / Time

I've used cProfile in the past, but I found line_profiler to be much more user friendly. It handles pretty much everything for you and only requires adding a @profile decorator to the function to target.

The package is called line_profiler but the executable is kernprof, and it is run with this command:

kernprof -v -l script_to_profile.py 

Memory

Memory profiling has proved to be much more difficult. I've used memory_profiler due to its similar API to line_profiler - you simply add the same @profile decorator to a function. However, the same code differs in memory measurement from run to run, so getting accurate results seems elusive.

This package is run with:

python -m memory_profiler script.py
