NAME

Bencher::Scenario::strftimeq - Benchmark strftimeq() routines

VERSION

This document describes version 0.001 of Bencher::Scenario::strftimeq (from Perl distribution Bencher-Scenario-strftimeq), released on 2019-11-20.

SYNOPSIS

To run benchmark with default option:

% bencher -m strftimeq

To run module startup overhead benchmark:

% bencher --module-startup -m strftimeq

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.

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

Date::strftimeq 0.001

DateTimeX::strftimeq 0.004

POSIX 1.65
