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 the suitable options enabled to allow a
|
|
proper operation of 'perf'.
