Linux Tools Project/PERF/User Guide
PERF is a performance counters subsystem in Linux. Performance counters are CPU hardware registers that count hardware events such as instructions executed and cache-misses suffered. These counters aid in profiling applications to detect hotspots in the application. PERF provides per task, per CPU and per-workload counters, sampling on top of these and source code event annotation.
The PERF plug-in for Eclipse allows the developer to execute profiles in their applications in a seamlessly way, using quick launch actions and visualizing the results in an user-friendly interface.
Launching a Profile
Perf plug-in provides useful profile information in a user-friendly interface, gathering the required information from the Perf command-line tool and hooking it into the Eclipse and CDT's facilities.
During a profile run, the Perf plug-in will start, stop and perform other Perf tasks in the background as needed, while the binary being profiled runs as normal.
