NAME
       perf - performance analysis tools for Linux

SYNOPSIS
       perf [--version] [--help] COMMAND [ARGS]

DESCRIPTION
       Performance  counters for Linux are are a new kernel-based subsystem that provide a frame‐
       work for all things performance analysis.  It covers hardware level (CPU/PMU,  Performance
       Monitoring Unit) features and software features (software counters, tracepoints) as well.

       Each  version  of  the perf tools may depend on new kernel features, so you must install a
       different version for each kernel version.  The perf command will  automatically  run  the
       correct version for the running kernel version.
