Profiling phat_small example

[jwuphysics]

I decided to profile (cProfile) the phat_small example using snakeviz (which is pip-installable). This is so that we can see which commands are running suboptimally.

# run profiler and save output to `phat_small.prof`
python -m cProfile -o phat_small.prof run_beast.py -potf

# launch server that displays results
snakeviz phat_small.prof

This displays something like:

We can focus on only the run_fitting method, which should be called multiple times in the production runs:

It also outputs the longest calls (per call):

Eventually this might be useful for optimizing specific functions.
