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