NAME

Bencher::Scenario::SetComparison - Benchmark set comparison

VERSION

This document describes version 0.003 of Bencher::Scenario::SetComparison (from Perl distribution Bencher-Scenario-SetComparison), released on 2017-01-25.

SYNOPSIS

To run benchmark with default option:

 % bencher -m SetComparison

To run module startup overhead benchmark:

 % bencher --module-startup -m SetComparison

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

DESCRIPTION

TODO: include more set modules.

TODO: compare complex elements.

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.

Test::Deep 1.120

Set::Tiny 0.04

BENCHMARK PARTICIPANTS

• Test::Deep (perl_code)

  Code template:

   state $set = Test::Deep::set(@{<set>}); Test::Deep::eq_deeply(<array>, $set)

• Set::Tiny (perl_code) [simple-elements]

  Code template:

   state $set1 = Set::Tiny->new(@{<array>}); state $set2 = Set::Tiny->new(@{<set>}); $set1->symmetric_difference($set2)->size == 0 ? 1:0

BENCHMARK DATASETS

• elems=10num

• elems=100num

• elems=200num
