Two sets of information are given in the duration measurement report: module
duration and module usage.
The first set of information in the duration measurement report is the "module
duration" measurement. The module duration report shows that the amount of time
it takes for the interrupt_sim function to execute varies from 39.8 microseconds to
592 milliseconds. The average amount of time it takes for the interrupt_sim module
to execute is roughly 63.6 milliseconds.
The second set of information in the duration measurement report is the "module
usage" measurement. Module usage measurements show how much time is spent
outside the module of interest; they indicate how often the module is used. The
information shown in the first part of the duration report above shows that the
average amount of time spent outside the interrupt_sim function is about 109.6
milliseconds.
