+ Shell command for Displaying Performance Metrics.
+
+ The Dp command reads performance data and presents it in several
+ different formats depending upon the needs of the user. Both
+ Trace and Measured Profiling information is processed and presented.
+
+ Dp uses the "PerformanceLib" to read the measurement records.
+ The "TimerLib" provides information about the timer, such as frequency,
+ beginning, and ending counter values.
+ Measurement records contain identifying information (Handle, Token, Module)
+ and start and end time values.
+ Dp uses this information to group records in different ways. It also uses
+ timer information to calculate elapsed time for each measurement.
