NAME

Bencher::Scenario::SortKeyTop - Benchmark Sort::Key::Top

VERSION

This document describes version 0.001 of Bencher::Scenario::SortKeyTop (from Perl distribution Bencher-Scenario-SortKeyTop), released on 2016-11-13.

SYNOPSIS

To run benchmark with default option:

% bencher -m SortKeyTop

To run module startup overhead benchmark:

% bencher --module-startup -m SortKeyTop

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.

BENCHMARKED MODULES

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

Sort::Key::Top 0.08

Sort::Key::Top::PP 0.003

BENCHMARK PARTICIPANTS

  • sort (perl_code)

    Perl's sort() builtin.

    Code template:

    state $elems=<elems>; my @sorted = sort { $a <=> $b } @$elems; splice @sorted, 0, <n>

  • Sort::Key::Top (perl_code)

    Function call template:

    Sort::Key::Top::nkeytopsort(sub { $_ }, <n>, @{<elems>})

  • Sort::Key::Top::PP (perl_code)

    Function call template:

    Sort::Key::Top::PP::nkeytopsort(sub { $_ }, <n>, @{<elems>})

BENCHMARK DATASETS

  • elems=10 , n=5

  • elems=100, n=10

  • elems=1000, n=10
