NAME Bencher::Scenario::File::Which::Cached - Benchmark File::Which::Cached VERSION This document describes version 0.002 of Bencher::Scenario::File::Which::Cached (from Perl distribution Bencher-Scenario-File-Which-Cached), released on 2022-03-19. SYNOPSIS To run benchmark with default option: % bencher -m File::Which::Cached To run module startup overhead benchmark: % bencher --module-startup -m File::Which::Cached 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.

Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via: % prove -l If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla plugin and/or Pod::Weaver::Plugin. Any additional steps required beyond that are considered a bug and can be reported to me. COPYRIGHT AND LICENSE This software is copyright (c) 2022, 2019 by perlancar .
