NAME

Bencher::Scenario::Log::ger::NumericLevel - Benchmark numeric_level()

VERSION

This document describes version 0.019 of Bencher::Scenario::Log::ger::NumericLevel (from Perl distribution Bencher-Scenarios-Log-ger), released on 2023-10-29.

SYNOPSIS

To run benchmark with default option:

% bencher -m Log::ger::NumericLevel

To run module startup overhead benchmark:

% bencher --module-startup -m Log::ger::NumericLevel

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.

Log::ger::Util 0.040

BENCHMARK PARTICIPANTS

  • Log::ger::Util::numeric_level (perl_code)

BENCHMARK SAMPLE RESULTS

Sample benchmark #1

Run on: perl: v5.38.0, CPU: Intel(R) Core(TM) i5-7200U CPU @ 2.50GHz (2 cores), OS: GNU/Linux Ubuntu version 20.04, OS kernel: Linux version 5.4.0-164-generic.

Benchmark command (default options):

% bencher -m Log::ger::NumericLevel

Result formatted as table:

#table1#
+---------+-----------+-----------+-----------------------+-----------------------+---------+---------+
| dataset | rate (/s) | time (ns) | pct_faster_vs_slowest | pct_slower_vs_fastest |  errors | samples |

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.
