Elapsed time, the total time your target ran, is calculated as follows:
Wall clock time at end of application – Wall clock time at start of application
Before you run a fixed workload (benchmark) reduce the Elapsed time for your target. A fixed workload does not depend on time and performs the same actions each time it runs.
The Estimated Call Count metric provides a statistical estimation of call counts based on hardware events.
This metric is available in the Hotspots viewpoint if you enabled the Estimate call counts option in the hardware event-based sampling analysis configuration.
