Bencher::Scenario::SPVM::Prime - Benchmark SPVM (check if number is prime)
This document describes version 0.008 of Bencher::Scenario::SPVM::Prime (from Perl distribution Bencher-Scenarios-SPVM), released on 2022-11-24.
To run benchmark with default option:
% bencher -m SPVM::Prime
For more options (dump scenario, list/include/exclude/add participants, list/include/exclude/add datasets, etc), see bencher or run bencher --help.
bencher --help
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.
Version numbers shown below are the versions used when running the sample benchmark.
SPVM 0.9662
SPVM::Examples 0.004
Inline::C (perl_code)
Perl (perl_code)
SPVM (perl_code)
SPVM_precompile (perl_code)
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 with default options (bencher -m SPVM::Prime):
bencher -m SPVM::Prime

To display as an interactive HTML table on a browser, you can add option --format html+datatables.
--format html+datatables
In this case, SPVM offers ~2x speed-up and near the performance of C code with precompilation.
My general impression on SPVM (Nov 2022, v0.9662): the parser is currently still buggy (e.g. insignificant whitespace causing syntax error). The significant speed-up and native compilation are nice features. If the language proves to be convenient enough for Perl programmers, it might become a useful addition to their toolbox.

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, Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps required beyond that are considered a bug and can be reported to me.
