Exclusive Method Times (CPU)
Use this visualizer to see CPU time spent by methods found in the captured data. CPU time
spent is given in milliseconds, and for each method, as a percentage of all CPU time used during
the capture period. Times are exclusive times.
A remark "(virtual times)" may be displayed after the metric title, if the collected times
are virtual CPU times.
The methods are sorted by decreasing time spent in CPU. The gray horizontal bars provide a
graphical representation of the time a method spent (in milliseconds) for the period of the collected
sample.
Other data shown include packages and arguments associated with each method.

Exclusive Method Clock Times
The standard Java methods java.lang.Thread.sleep and java.lang.Object.wait are
not included in this metric. This is because usually the time spent in these methods is a few orders
of magnitude larger than in any other method. At the same time, the total time spent in sleep or
wait has hardly any relationship to any possible performance bottlenecks, and including these
two methods would only distract the user.
