oprofile is:
OProfile is a performance profiling tool for Linux systems, capable of profiling all running code at low overhead. It consists of a daemon for collecting sample data, plus several post-profiling tools for turning data into information.
OProfile leverages the hardware performance counters of the CPU to enable profiling of a wide variety of interesting statistics, which can also be used for basic time-spent profiling. All code is profiled: hardware and software interrupt handlers, kernel modules, the kernel, shared libraries, and applications (the only exception being the OProfile interrupt handler itself).
