Hyperfine

Hyperfine is a benchmarking tool.

Usage

Benchmark One or More Programs

To benchmark a program it is recommended to warm up the cache before. This can be done as shown in the following command.

hyperfine --warmup 5 'sleep 0.3'

Unless specified otherwise at least 10 runs will be made to benchmark a program. To change this the --runs flag can be used. An example of it is given in the following command.

hyperfine --warmup 5 --runs 3 'sleep 0.3'

To compare two programs simply append the program to compare to as shown in the following command.

hyperfine --warmup 5 'sleep 0.3' 'sleep 0.4'
