Versions:
WindowsPerf is a Linux-perf-inspired performance profiling utility developed by Arm, specifically engineered to analyze and optimize software execution on Windows-on-Arm devices. Currently at version 5.5.0 after eleven incremental releases, the tool samples hardware counters, call stacks, and kernel events to reveal CPU bottlenecks, cache behavior, branch mispredictions, and power consumption patterns in native Arm64 applications, emulated x86 binaries, and mixed workloads. Developers use it during driver tuning, game-engine porting, and high-performance library optimization, while researchers leverage its time-based and event-based metrics to validate micro-architectural improvements on Snapdragon, Microsoft SQ-series, and other Arm-based laptops and servers. The command-line interface supports both statistical sampling and precise event tracing, exporting data to JSON or CSV for further visualization in Python, MATLAB, or Grafana; integration with Visual Studio and VS Code extensions enables source-level annotation without leaving the IDE. Because WindowsPerf is aware of WoW64 translation layers, it can attribute stalls to emulation overhead and guide decisions on re-compiling code paths for native performance. Typical sessions run on release or debug builds, with negligible overhead when sampling at 1 KHz and moderate overhead during aggressive 8 KHz collection, making the tool suitable for continuous-integration benchmarks as well as late-stage polish. The software is available for free on get.nero.com, with downloads provided via trusted Windows package sources (e.g. winget), always delivering the latest version, and supporting batch installation of multiple applications.
