NAME
Bencher::Scenario::ListMoreUtils - Benchmark List::MoreUtils::PP vs List::MoreUtils::XS
VERSION
This document describes version 0.04 of Bencher::Scenario::ListMoreUtils (from Perl distribution Bencher-Scenario-ListMoreUtils), released on 2017-01-25.
SYNOPSIS
To run benchmark with default option:
% bencher -m ListMoreUtilsTo run module startup overhead benchmark:
% bencher --module-startup -m ListMoreUtilsFor more options (dump scenario, list/include/exclude/add participants, list/include/exclude/add datasets, etc), see bencher or run bencher --help.
DESCRIPTION
EARLY VERSION, ONLY A FEW FUNCTIONS HAVE BEEN BENCHMARKED.
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.
