NAME

Bencher::Scenario::TimeDurationParse::parse_duration - Benchmark parse_duration()

VERSION

This document describes version 0.002 of Bencher::Scenario::TimeDurationParse::parse_duration (from Perl distribution Bencher-Scenarios-TimeDurationParse), released on 2017-01-25.

SYNOPSIS

To run benchmark with default option:

 % bencher -m TimeDurationParse::parse_duration

To run module startup overhead benchmark:

 % bencher --module-startup -m TimeDurationParse::parse_duration

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.

To display as an interactive HTML table on a browser, you can add option --format html+datatables.

BENCHMARK NOTES

Time::Duration::Parse::AsHash is expected to be slightly slower since it needs to build and return a hashref instead of a single number.
