Hyperfine is a command-line tool designed for benchmarking shell commands and arbitrary programs. It automatically performs multiple timing runs, calculates statistical measures, and provides detailed reports. Hyperfine excels at identifying performance bottlenecks and comparing the efficiency of different approaches, leveraging Rust for speed and reliability.
Hyperfine stands out with its statistical analysis of benchmark results, offering insights beyond simple average times. The ability to warmup programs and incorporate preparation commands ensures accurate timing by accounting for factors like cache effects and setup times. Its support for parameterized benchmarks enables comprehensive performance testing across different configurations.
- Statistical Analysis: Provides mean, minimum, maximum, and standard deviation for a more complete performance picture.
- Warmup Runs: Allows for warmup iterations to stabilize timing results and eliminate initial overhead.
- Parameterized Benchmarking: Enables running benchmarks with varying parameters, such as thread counts or input sizes.
- Export Results: Supports exporting results in CSV, JSON, and Markdown formats for easy analysis and visualization.
- Shell Correction: Accurately measures command execution time by correcting for shell startup overhead.
- Cross-Platform: Available on Linux, macOS, and Windows, with pre-built packages for various distributions.
- Flexible Shell Support: Supports execution with different shells including bash, zsh and without a shell.
Hyperfine is a well-established project with active maintenance and a large user base. It has a consistent release history and a responsive community. The project is actively developed with frequent updates and bug fixes, and its comprehensive documentation and examples contribute to its reliability.
Hyperfine benefits developers, system administrators, and performance engineers by providing a robust and accurate benchmarking solution.
