Results

There are 3 sections in the resulting output file of this stochastic quick analysis.

1. The first section is a histogram of the timer intervals of that sample set. Each function occupies a region of addresses. One hundred times a second, the profiler samples the program address in the region of execution.
2. In the second section, there is another histogram of the cumulative frequency of all things in the call stack and this should point out who is the culprit. For example, a codec calls a bunch of subroutines, the cost of the subroutines is accumulated to the codec parent caller. This makes the actual cpu user much more apparent.
3. The last section is for the library spaces. Each library occupies a region and the profiler adds up the time spent in each of the libraries by frequency.

On the very bottom is a 1 line summary which shows you if there is a bad guy and who it is.
