NAME

Bencher::Scenario::DataUndump - Benchmark Data::Undump against eval() for loading a Data::Dumper output

VERSION

This document describes version 0.001 of Bencher::Scenario::DataUndump (from Perl distribution Bencher-Scenario-DataUndump), released on 2019-09-07.

SYNOPSIS

To run benchmark with default option:

% bencher -m DataUndump

To run module startup overhead benchmark:

% bencher --module-startup -m DataUndump

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.

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 DataUndump):

Benchmark module startup overhead (bencher -m DataUndump --module-startup):

#table2#
+---------------------+-----------+------------------------+------------+---------+---------+
