Making Software Performance Measurements
To interpret duration measurement reports
Two sets of information are given in the duration measurement report:
module duration and module usage.
The first 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
first part of the duration report above shows that the average amount of time
spent outside the interrupt_sim function is about 55.7 milliseconds.
The second 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
52.3 microseconds to 342.3 milliseconds. The average amount of time it takes
for the interrupt_sim module to execute is roughly 37 milliseconds.
