Interpreting Reports Of Activity Measurements; Memory Activity - HP 64700 Series User Manual

4-12 Performance Measurements
-p Produce a summary limited to the program
activity.
-m Produce a summary limited to the memory
activity.
-f< file> Produce a report based on the information
contained in < file> instead of the
information contained in perf.out.
For example, the following commands save the current
performance measurement information in a file called "perf1.out",
and produce a histogram showing only the program activity
occupied by the functions and variables.
mv perf.out perf1.out <RETURN>
perf32 -hpf perf1.out <RETURN>
Options -h, -s, -p, and -m affect the contents of reports generated
for activity measurements. These options have no effect on the
contents of reports generated for duration (time interval)
measurements.

Interpreting Reports of Activity Measurements

Activity measurements are measurements of the number of
accesses (reads or writes) within an address range. The reports
generated for activity measurements show you the percentage of
analyzer trace states that are in the specified address range, as well
as the percentage of time taken by those states. The performance
measurement must include four traces before statistics ( mean and
standard deviation) appear in the activity report. The information
you will see in activity measurement reports is described below.
Memory Activity. All activity found within the address range.
Program Activity. All activity caused by instruction execution in
the address range. Program activity includes opcode fetches and
the cycles that result from the execution of those instructions
(reads and writes to memory, stack pushes, etc.).
