NAME Bencher::Scenario::RandomLineModules - Benchmark modules which pick random line(s) from a file VERSION This document describes version 0.05 of Bencher::Scenario::RandomLineModules (from Perl distribution Bencher-Scenario-RandomLineModules), released on 2017-07-10. SYNOPSIS To run benchmark with default option: % bencher -m RandomLineModules To run module startup overhead benchmark: % bencher --module-startup -m RandomLineModules For more options (dump scenario, list/include/exclude/add participants, list/include/exclude/add datasets, etc), see bencher or run "bencher --help". DESCRIPTION Packaging a benchmark script as a Bencher scenario makes it convenient to include/exclude/add participants/datasets (either via CLI or Perl code), send the result to a central repository, among others . See Bencher and bencher (CLI) for more details. BENCHMARKED MODULES Version numbers shown below are the versions used when running the sample benchmark.
