perf - performance analysis tools for Linux
perf [--version] [--help] COMMAND [ARGS]
Performance counters for Linux are are a new kernel-based subsystem
that provide a framework 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.
