NAME

Bencher::Scenario::PackageMoreUtil::package_exists - Benchmark package_exists()

VERSION

This document describes version 0.002 of Bencher::Scenario::PackageMoreUtil::package_exists (from Perl distribution Bencher-Scenarios-PackageMoreUtil), released on 2018-10-07.

SYNOPSIS

To run benchmark with default option:

 % bencher -m PackageMoreUtil::package_exists

To run module startup overhead benchmark:

 % bencher --module-startup -m PackageMoreUtil::package_exists

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.
