sysprof 3.45.1 System-wide performance profiler for GNU/Linux
Sysprof performs detailed, accurate, and fast CPU profiling of an entire GNU/Linux system including the kernel and all user-space applications. This helps find the function(s) in which a program spends most of its time.
It uses the kernel's built-in
ptrace feature and handles shared libraries. Applications do not need to be recompiled--or even restarted.
