The Statistics tab shows totals for various system statistics summed over the selected experiments and samples followed by the statistics for the selected samples of each experiment. The process times are summed over the microaccounting states in the same way that metrics are summed. See Timing Metrics for more information.
The statistics displayed in the Statistics tab should in general match the timing metrics displayed for the <Total> function in the Functions tab. The values displayed in the Statistics tab are more accurate than the microstate accounting values for <Total>. But in addition, the values displayed in the Statistics tab include other contributions that account for the difference between the timing metric values for <Total> and the timing values in the Statistics tab. These contributions come from the following sources:
