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 --min-runs 7 'make'

• Perform benchmark with warmup:

hyperfine --warmup 5 'make'

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

hyperfine --prepare 'make clean' 'make'

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

hyperfine --prepare 'make clean' --parameter-scan num_threads 1 10 'make -j {num_threads}'
