Bencher::Scenario::Perl::Startup - Benchmark startup time of perls
This document describes version 0.054 of Bencher::Scenario::Perl::Startup (from Perl distribution Bencher-Scenario-Perl-Startup), released on 2023-07-08.
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.
bencher --help
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.

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.
