Profiling/Benchmarking Tools C++ Profilers C++ Profilers

Profiling Applications Applications

GNU Profiler (gprof)	ubiquitous free software some IDEs can present gprof results in a GUI
Intel VTune Profiler	free of charge GUI & command line interface sampling-based profiling hardware event sampling for Intel chips locks & waits analysis memory access analysis storage analysis integrates with MS Visual Studio
Coz – Causal Profiler	unique approach to profiling creates causal profile: "optimizing function X will have effect Y" profile is based on performance experiments program is partitioned into parts based on progress points (that are set in source code) no additional instrumentation of source code required
