NAME
Bencher::Scenario::Digest - Benchmark various digest algorithms
VERSION
This document describes version 0.001 of Bencher::Scenario::Digest (from Perl distribution Bencher-Scenario-Digest), released on 2017-03-07.
SYNOPSIS
To run benchmark with default option:
% bencher -m Digest
To run module startup overhead benchmark:
% bencher --module-startup -m Digest
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.
Digest::MD5 2.54
Digest::SHA 5.95
BENCHMARK PARTICIPANTS
md5 (perl_code)
Code template:
my $ctx = Digest::MD5->new; $ctx->add($main::data1M) for 1..<size>; $ctx->hexdigest
sha1 (perl_code)
Code template:
my $ctx = Digest::SHA->new(1); $ctx->add($main::data1M) for 1..<size>; $ctx->hexdigest
sha256 (perl_code)
Code template:
my $ctx = Digest::SHA->new(256); $ctx->add($main::data1M) for 1..<size>; $ctx->hexdigest
sha512 (perl_code)
Code template:
my $ctx = Digest::SHA->new(512); $ctx->add($main::data1M) for 1..<size>; $ctx->hexdigest
BENCHMARK DATASETS
10M
