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 82.6 microseconds to
253.2 milliseconds. The average amount of time it takes for the interrupt_sim
module to execute is roughly 28 milliseconds.
The second set 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 second part of the duration
report above shows that the average amout of time spent outside the interrupt_sim
function is about 59.4 milliseconds.
