Profiling in visual studio

Somehow, I am often struggling to understand the output of profilers. This report of Visual Studio actually makes sense to me:

I like the code highlighting. It gives a really quick overview of where most of the time is spent. (Most of the time in parsing some files is spent in dealing with the regular expression; I am happy: no obviously poor performance somewhere in my code. Interestingly, also when parsing the Excel formulas I spent most of the time parsing Excel addresses – again using a regular expression.)
