NAME Bencher::Scenario::Digest::SHA1 - Benchmark Digest::SHA1 against Digest::SHA VERSION This document describes version 0.004 of Bencher::Scenario::Digest::SHA1 (from Perl distribution Bencher-Scenario-Digest-SHA1), released on 2022-03-19. SYNOPSIS To run benchmark with default option: % bencher -m Digest::SHA1 To run module startup overhead benchmark: % bencher --module-startup -m Digest::SHA1 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::SHA1 2.13 Digest::SHA 6.02 BENCHMARK PARTICIPANTS * Digest::SHA1 (perl_code) Code template: my $ctx = Digest::SHA1->new; open my $fh, "<", ; $ctx->addfile($fh); $ctx->hexdigest * Digest::SHA (perl_code) Code template: my $ctx = Digest::SHA->new(1); open my $fh, "<", ; $ctx->addfile($fh); $ctx->hexdigest BENCHMARK DATASETS * 30M_file SAMPLE BENCHMARK RESULTS Run on: perl: *v5.34.0*, CPU: *Intel(R) Core(TM) i5-7200U CPU @ 2.50GHz (2 cores)*, OS: *GNU/Linux Ubuntu version 20.04*, OS kernel: *Linux version 5.4.0-91-generic*.

BENCHMARK NOTES Digest::SHA is faster than Digest::SHA1, so in general there is no reason to use Digest::SHA1 over Digest::SHA (core module, more up-to-date, support more algorithms).

AUTHOR perlancar CONTRIBUTING To contribute, you can send patches by email/via RT, or send pull requests on GitHub. Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via: % prove -l If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla plugin and/or Pod::Weaver::Plugin. Any additional steps required beyond that are considered a bug and can be reported to me. COPYRIGHT AND LICENSE This software is copyright (c) 2022, 2017 by perlancar .
