NAME
Bencher::Scenario::DataCmp - Benchmark Data::Cmp against similar solutions
VERSION
This document describes version 0.001 of Bencher::Scenario::DataCmp (from Perl distribution Bencher-Scenario-DataCmp), released on 2018-12-06.
SYNOPSIS
To run benchmark with default option:
% bencher -m DataCmp
To run module startup overhead benchmark:
% bencher --module-startup -m DataCmp
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.
