NAME
Bencher::Scenario::SortKeyTop - Benchmark Sort::Key::Top
VERSION
This document describes version 0.002 of Bencher::Scenario::SortKeyTop (from Perl distribution Bencher-Scenario-SortKeyTop), released on 2017-01-25.
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
