	  perf (sometimes "Perf Events" or perf tools, originally
	  "Performance Counters for Linux") - is a performance
	  analyzing tool in Linux, available from kernel version
	  2.6.31. User-space controlling utility, called 'perf' has
	  git-like interface with subcommands. It is capable of
	  statistical profiling of entire system (both kernel and user
	  code), single CPU or severals threads.

	  command. It is up to the user to ensure that the kernel
	  configuration has all suitable options enable to allow a
	  proper operation of 'perf'.
