NAME Bencher::Scenario::Perl::Startup - Benchmark startup time of perls VERSION This document describes version 0.051 of Bencher::Scenario::Perl::Startup (from Perl distribution Bencher-Scenario-Perl-Startup), released on 2021-06-10. 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.
