NAME

Bencher::Scenario::StringModules::Startup - Benchmark startup of string modules

VERSION

This document describes version 0.004 of Bencher::Scenario::StringModules::Startup (from Perl distribution Bencher-Scenarios-StringFunctions), released on 2021-07-30.

SYNOPSIS

To run benchmark with default option:

 % bencher -m StringModules::Startup

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

DESCRIPTION

Packaging a benchmark script as a Bencher scenario makes it convenient to include/exclude/add participants/datasets (either via CLI or Perl code), send the result to a central repository, among others . See Bencher and bencher (CLI) for more details.
