hyperfine/scripts

This folder contains scripts that can be used in combination with hyperfine's --export-json option.

Run directly from GitHub

Install uv, then run one of the scripts:

hyperfine 'sleep 0.020' 'sleep 0.021' 'sleep 0.022' --export-json sleep.json
uvx --from 'git+https://github.com/sharkdp/hyperfine' \
  plot_whisker sleep.json

Replace plot_whisker with any of the following commands.

Command	Description
plot_whisker	Compare benchmarks with a box and whisker plot
plot_histogram	Show the distribution of measurements
plot_parametrized	Plot results from a parameter scan
plot_progression	Show measurements in run order
plot_benchmark_comparison	Compare commands across multiple JSON exports
advanced_statistics	Print additional statistics and percentiles
welch_ttest	Compare two benchmarks using Welch's t-test

By default, the plotting and analysis scripts use the metric that was selected first in the actual hyperfine run (--metrics option). Use --metric to select another metric:

uvx --from 'git+https://github.com/sharkdp/hyperfine' \
  plot_histogram benchmark.json --metric instructions
