Bencher::Scenario::LogGer::StringLevel - Benchmark string_level()

VERSION

This document describes version 0.018 of Bencher::Scenario::LogGer::StringLevel (from Perl distribution Bencher-Scenarios-LogGer), released on 2021-04-09.

SYNOPSIS

To run benchmark with default option:

% bencher -m LogGer::StringLevel

To run module startup overhead benchmark:

% bencher --module-startup -m LogGer::StringLevel

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

DESCRIPTION
