pmc -- performance-monitoring counter interface for command execution
pmc -h pmc -C pmc -c event command [options ...]
pmc is a means of using a processor's performance-monitoring counter (PMC) facility to measure various aspects of a program's execution. It is meant to be used in a fashion similar to time(1). The arguments are as follows: -h Display a list of performance counter events available on the system. -C Cancel any performance counters that are currently running. -c event Count the event specified by event while running the command.
PMC support is not compiled into the kernel Performance-monitoring counter support has not been compiled into the kernel. It may be included using the PERFCTRS option. See options(4) for details. PMC counters are not supported by CPU Performance-monitoring counters are not available for the CPU.
