NAME

Bencher::Scenario::DateTimeOfDay::format - Benchmark timeofday formatting

VERSION

This document describes version 0.001 of Bencher::Scenario::DateTimeOfDay::format (from Perl distribution Bencher-Scenarios-DateTimeOfDay), released on 2019-02-07.

SYNOPSIS

To run benchmark with default option:

% bencher -m DateTimeOfDay::format

To run module startup overhead benchmark:

% bencher --module-startup -m DateTimeOfDay::format

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.

Date::TimeOfDay 0.005

BENCHMARK PARTICIPANTS

  • hms (perl_code)

    Code template:

    state $tod = Date::TimeOfDay->from_float(float=>86399); $tod->hms

  • stringify (perl_code)

    Code template:

    state $tod = Date::TimeOfDay->from_float(float=>86399); $tod->stringify

SAMPLE BENCHMARK RESULTS

Run on: perl: v5.26.1, CPU: Intel(R) Core(TM) M-5Y71 CPU @ 1.20GHz (2 cores), OS: GNU/Linux LinuxMint version 18.3, OS kernel: Linux version 4.10.0-38-generic.

Benchmark with default options (bencher -m DateTimeOfDay::format):
