Tool of the Day: OProfile
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). Note that different
architectures can use different hardware mechanisms to collect
data.
version: OProfile 0.9.8
