NAME

Bencher::Scenario::GraphTopologicalSortModules - Benchmark graph topological sort modules

VERSION

This document describes version 0.005 of Bencher::Scenario::GraphTopologicalSortModules (from Perl distribution Bencher-Scenario-GraphTopologicalSortModules), released on 2019-02-15.

SYNOPSIS

To run benchmark with default option:

 % bencher -m GraphTopologicalSortModules

To run module startup overhead benchmark:

 % bencher --module-startup -m GraphTopologicalSortModules

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.

BENCHMARKED MODULES

Version numbers shown below are the versions used when running the sample benchmark.

Algorithm::Dependency 1.111

Data::Graph::Util 0.006
