Example of Using the Profiler to Help Reduce the Execution Time of a Function

I have a function which analyzes the contents of a few hundred folders. Its taking several minutes to run and I use it a lot, so I want to try and make it execute faster.

I propose using the profiler to try and understand where the time is spent and explore some code changes.

I often find with my performance improvement work, that the first changes I make are to my algorithm, or code architecture. For example, by ensuring that I only execute the computations that I need to. Later, I might then look at speeding up those computations.
