README

Latest Stable Version License

nochso/benchmark creates pretty HTML benchmarks from any closures you supply:

  • Generate HTML reports including Github flavoured Markdown
  • Reliably compare different algorithms
  • Run tests for a minimum amount of time to ensure stable results

Installation

  1. Install composer on Linux / Unix / OSX or Windows

  2. Require this package via composer:

    composer require nochso/benchmark

Usage

Have a look at the example reports.

A very simple example without parameters:

$report = new Report('My report name');
$unit = new Unit('Encryption speed');
$unit->addClosure(function ($n) {
    while ($n--) {
        $x = str_rot13('secret');
    }
}, 'rot13');
$unit->addClosure(function ($n) {
    while ($n--) {
        $x = str_rot13(str_rot13('secret'));
    }
}, 'rot26');
$report->unitList->add($unit);
$report->run();

This will generate and save a HTML report to folder build by default.

Options

The Report constructor takes an optional third argument $config:

public function __construct($title, $description = '', $config = array())

If omitted, default options will be used. Otherwise your configuration will be merged with the defaults.

array(
    'template_dir' => 'template',
    'output_dir'   => 'build',
    'twig'         => array(
        'cache'            => 'cache/twig',
        'auto_reload'      => true,
        'strict_variables' => true,
    ),
)

You can also change the minimum duration of tests which defaults to 1000 millseconds (1 second):

\nochso\Benchmark\Timer::$defaultMinDuration = 1000;
