    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
    Tracy
    • integrates with apps on source-code level
    • client-server architecture for remote profiling
    • real-time profiling with nanosecond resolution
    • memory allocations, locks, context switches
    • possible to profile OpenGL, Vulkan, Direc3d, OpenCL
    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
    perf
    Valgrind (cachegrind, callgrind)
    Xperf

    part of the ADK (Windows Assessment and Deployment Kit)

    Apple Instruments
    • part of XCode
    NVIDIA Nsight Compute
    • profiling for NVIDIA GPUs (architectures: Pascal, Volta, Turing)
    • supplants NVIDIA Visual Profiler
    AMD uProf
    • sampling profiler for AMD CPUs and some AMD GPUs
    • instruction based sampling, micro-architecture analysis,
    • call stack sampling, timer-based profiling
    • cache analysis, power profiling
    DTrace
    Very Sleepy
    • sampling CPU profiler
    • support for MinGW
    • late symbol resolution
    Optick
    • instrumentation-based and sampling-based profiling
    • GPU counters
    OProfile
    GlowCode
    SmartBear AQTime
    Arm MAP
    Oracle Performance Analyzer
    Easy Profiler

    Benchmarking Libraries / Frameworks Libraries / Frameworks Libraries

    • Apache-2.0
    Google Benchmark
    • BSD-3-Clause
    gperftools

    (originally Google Performance Tools)

    • high-performance multithreaded malloc()
    • heap checker
    • heap profiler
    • cpu profiler
    • Apache-2.0
    Celero
    • zlib
    plf::nanotimer

    simple, cross-platform microsecond-precision timer class

    • BSL-1.0
    Catch2

    unit testing framework that also includes timing primitives

    Timing Tools

    Hyperfine

    Benchmarking of executables similar to the classic 'time' command but much more sophisticated.

    • statistical analysis across multiple runs
    • support for arbitrary shell commands
    • constant feedback about the benchmark progress and current estimates
    • warmup runs can be executed before the actual benchmark
    • cache-clearing commands can be set up before each timing run
    • statistical outlier detection to detect interference from other programs and caching effects
    • export results to various formats: CSV, JSON, Markdown, AsciiDoc
    • parameterized benchmarks (e.g. vary the number of threads)
    • cross-platform
