How to use the Session Frontend Profiler?

Hi everyone!

I am currently working on my first app and now I want to know how I can streamline my project.

I am not that good at programming and so the output of my profiler does not help me alot, because I don’t know what all those events do that are listed.
When I was playing the app on my smartphone I ran the datacapture and this is one frame where I switched between two FileMediaSources:

Can someone please tell me what all those “wait for event” lines are?
Does anybody have a good tutorial or so that can help me to understand what those lines are and what I have to look out for?

Cheers and wonderful holidays to you all :wink:
