NAME

Bencher::Scenario::ArrayVsHashBuilding - Benchmark building array vs hash

VERSION

This document describes version 0.001 of Bencher::Scenario::ArrayVsHashBuilding (from Perl distribution Bencher-Scenario-ArrayVsHashBuilding), released on 2016-09-03.

SYNOPSIS

To run benchmark with default option:

% bencher -m ArrayVsHashBuilding

For more options (dump scenario, list/include/exclude/add participants, list/include/exclude/add datasets, etc), see bencher or run bencher --help.

BENCHMARK PARTICIPANTS

  • array (perl_code)

    Code template:

    state $elems=<elems>; my $ary = []; for my $elem (@$elems) { push @$ary, $elems }; $ary

  • hash (perl_code)

    Code template:

    state $elems=<elems>; my $hash = {}; for my $elem (@$elems) { $hash->{$elem} = 1 }; $hash

BENCHMARK DATASETS

  • elems=1

  • elems=10

  • elems=100

  • elems=1000

  • elems=10000

SAMPLE BENCHMARK RESULTS

Run on: perl: v5.22.1, CPU: Intel(R) Core(TM) M-5Y71 CPU @ 1.20GHz (2 cores), OS: GNU/Linux LinuxMint version 17.3, OS kernel: Linux version 3.19.0-32-generic.

Benchmark with default options (bencher -m ArrayVsHashBuilding):

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.
