Flame chart

This tab of the profiler shows CPU samples for the recorded duration.
This chart should be viewed as a top-down stack trace, where the
top-most stack frame calls the one below it. The width of each stack
frame represents the amount of time it consumed the CPU. Stack frames
that consume a lot of CPU time might be a good place to look for possible
performance improvements.

Call tree

The call tree view shows the method trace for the CPU profile.
This table is a top-down representation of the profile,
meaning that a method can be expanded to show its callees.

Time the method spent executing its own code as well as
    the code for its callees.

Time the method spent executing only its own code.

Name of the called method.

File path for the method call site.
