help
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.
This package builds and install the userspace 'perf'
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'.
