NAME
Bencher::Scenario::ModuleInstalledTiny::module_source - Benchmark Module::Installed::Tiny's module_source()
VERSION
This document describes version 0.004 of Bencher::Scenario::ModuleInstalledTiny::module_source (from Perl distribution Bencher-Scenarios-ModuleInstalledTiny), released on 2020-01-14.
SYNOPSIS
To run benchmark with default option:
% bencher -m ModuleInstalledTiny::module_source
To run module startup overhead benchmark:
% bencher --module-startup -m ModuleInstalledTiny::module_source
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.

SAMPLE BENCHMARK RESULTS
Run on: perl: v5.30.0, CPU: Intel(R) Core(TM) i5-7200U CPU @ 2.50GHz (2 cores), OS: GNU/Linux Ubuntu version 19.04, OS kernel: Linux version 5.0.0-37-generic.
Benchmark with default options (bencher -m ModuleInstalledTiny::module_source
):

To display as an interactive HTML table on a browser, you can add option --format html+datatables
.
BENCHMARK NOTES
`module_source()` is slower than `require()` by about 15%.
