NAME
Bencher::Scenario::ArrayVsHashBuilding - Benchmark building array vs hash
VERSION
This document describes version 0.002 of Bencher::Scenario::ArrayVsHashBuilding (from Perl distribution Bencher-Scenario-ArrayVsHashBuilding), released on 2021-07-31.
SYNOPSIS
To run benchmark with default option:
% bencher -m ArrayVsHashBuildingFor 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.
BENCHMARK PARTICIPANTS
array (perl_code)
Code template:
state $elems=<elems>; my $ary = []; for my $elem (@$elems) { push @$ary, $elems }; $aryhash (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
BENCHMARK SAMPLE RESULTS
Sample benchmark #1

Benchmark command (default options):
% bencher -m ArrayVsHashBuildingResult formatted as table:
