hyperfine

A command-line benchmarking tool. More information: https://github.com/sharkdp/hyperfine/.

• Run a basic benchmark, performing at least 10 runs:

hyperfine '{{make}}'

• Run a comparative benchmark:

hyperfine '{{make target1}}' '{{make target2}}'

• Change minimum number of benchmarking runs:

hyperfine {{[-m|--min-runs]}} {{7}} '{{make}}'

• Perform benchmark with warmup:

hyperfine {{[-w|--warmup]}} {{5}} '{{make}}'

• Run a command before each benchmark run (to clear caches, etc.):

hyperfine {{[-p|--prepare]}} '{{make clean}}' '{{make}}'

• Run a benchmark where a single parameter changes for each run:

hyperfine {{[-p|--prepare]}} '{{make clean}}' {{[-P|--parameter-scan]}} {{num_threads}} {{1}} {{10}} '{{make {{[-j|--jobs]}} {num_threads}}}'
