I am trying to track down a slow script startup time. I have executed the
script using `python -m cProfile -o profile /path/script.py` and read through
the results, but the largest culprit only shows various built-ins.

I expected this given the implementation, but I was hoping to get some
finer details so I can track down the specific module or at least the specific
file so I have a place to start reviewing code for optimizations.

Is there something I can use to analyze the existing profile output or to generate
it with more feedback?

Thanks,
jlc

Are you accounting for how long it takes to start the Python
interpreter itself?
