hyperfine
A command-line benchmarking tool that performs statistical analysis across multiple runs to accurately measure and compare shell command execution times.
What is hyperfine?
hyperfine is a command-line benchmarking tool that measures and compares the execution time of shell commands. It solves the problem of unreliable one-off timing by running commands multiple times, performing statistical analysis, and correcting for overhead to provide accurate performance insights.
Developers, system administrators, and performance engineers who need to benchmark command-line tools, scripts, or system commands to optimize performance or compare alternatives.
Developers choose hyperfine for its statistical rigor, ease of use, and advanced features like warmup runs, outlier detection, and export options, which provide more reliable and actionable benchmarks than simple timing commands.
