NAME

Bencher::Scenario::Exporters::Startup - Benchmark the startup overhead of some exporter modules

VERSION

This document describes version 0.091 of Bencher::Scenario::Exporters::Startup (from Perl distribution Bencher-Scenarios-Exporters), released on 2019-08-16.

SYNOPSIS

To run benchmark with default option:

 % bencher -m Exporters::Startup

For more options (dump scenario, list/include/exclude/add participants, list/include/exclude/add datasets, etc), see bencher or run bencher --help.

DESCRIPTION

Some notes:

  • Exporter::Lite not so lite

    Despite the ::Lite in its name and having less features than Exporter, the startup overhead is worse than Exporter (mostly due to the use of warnings).

    Also, this module is no longer necessary since Exporter 5.57 (2004), since Exporter can be used without subclassing, all you have to do is:

     use Exporter qw(import);
