Measuring region occupancy

A measure of region activity is the percentage of region occupancy. This is broadly the ratio of the elapsed time a region is performing processing to the trace interval.

The region occupancy time does not include those times when no messages are available, when the block loading is delayed, or when the PSB cannot be used. The last section in the Region Summary report lists all active regions for which timed events were collected and shows the calculated percentage region occupancies.
