The raso tunables
As the root user, you can tune the instruction threshold with the tprof_inst_threshold tunable of the raso command.
As the root user, you can tune the sampling frequency with the
following raso tunables:
- tprof_cyc_mult
- tprof_evt_mult
For example, for events based on processor cycles, setting the tprof_cyc_mult tunable to 50 and specifying the -f flag as 100 is equivalent to specifying a sampling frequency of 100/50 milliseconds.
For other Performance Monitor events, setting the tprof_evt_mult tunable to 100 and specifying the -f flag as 20,000 is equivalent to specifying a sampling frequency of 20,000/100 occurrences.
