Working in Python 3.6, it's easy to profile function performance on toy examples or in a local development context. However, I needed to profile the performance of some functions in a production context. I couldn’t find any good tools for doing this, so I wrote my own. I present Function-Profiler, a lightweight module that records calls to functions as well as their execution times, and outputs statistics about them.

The GitHub repository, containing its documentation, is available here. Take a look! You can also install it directly via pip3 install function-profiler.
