NAME

Bencher::Scenario::Perl::Startup - Benchmark startup time of perls

VERSION

This document describes version 0.053 of Bencher::Scenario::Perl::Startup (from Perl distribution Bencher-Scenario-Perl-Startup), released on 2021-07-23.

SYNOPSIS

To run benchmark with default option:

% bencher -m Perl::Startup

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

DESCRIPTION

Conclusion: in general newer versions of perl has larger startup overhead than previous ones. If startup overhead is important to you, use -e instead of -E unless necessary.
