Interpreting Reports of Duration Measurements

Duration measurements provide a best-case/worst-case
characterization of code execution time. These measurements
record execution times that fall within a set of specified time
ranges. The information you will see in duration measurement
reports is described below.
Number of Intervals. Number of "from address" and "to address"
pairs (after prefetch correction).
Maximum Time. The greatest amount of time between the "from
address" to the "to address".
Minimum Time. The shortest amount of time between the "from
address" to the "to address".
Average Time. Average time between the "from address" and the
"to address". The following equation is used to calculate the

average time:
