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.

CONTRIBUTING

To contribute, you can send patches by email/via RT, or send pull requests on GitHub.

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.
