NAME

Bencher::Scenario::Log::ger::Overhead - Measure startup overhead of various codes

VERSION

This document describes version 0.020 of Bencher::Scenario::Log::ger::Overhead (from Perl distribution Bencher-ScenarioBundle-Log-ger), released on 2024-05-12.

SYNOPSIS

To run benchmark with default option:

% bencher -m Log::ger::Overhead

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, Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps required beyond that are considered a bug and can be reported to me.

BUGS

Please report any bugs or feature requests on the bugtracker website https://rt.cpan.org/Public/Dist/Display.html?Name=Bencher-ScenarioBundle-Log-ger

When submitting a bug or request, please include a test-file or a patch to an existing test-file that illustrates the bug or desired feature.
