PHP Benchmark Script

A simple script that calculate execution time of common control flows and function of the PHP. Helps you to compare performances of servers, web hosting and also across PHP versions.

Usage

From your SSH:

curl https://raw.githubusercontent.com/SergiX44/php-benchmark-script/master/bench.php | php

Or upload the file bench.php to your web document root and visit it.

Parameters

You can change the difficulty multiplier by passing a multiplier parameter:

php bench.php --multiplier=2

Additional tests

You must have the bench.php file to your server. You can download additional benchmarks (must be in the same directory as bench.php) using:

Available tests:

# rand: random number generation
wget https://raw.githubusercontent.com/SergiX44/php-benchmark-script/master/rand.bench.php
# io: file read/write/zip/unzip
wget https://raw.githubusercontent.com/SergiX44/php-benchmark-script/master/io.bench.php

Then you can run the benchmark using:

php bench.php

If the file is in the same directory as bench.php, it will be automatically loaded.

Custom tests

You can create your own tests by creating a file in the same directory as bench.php and the file must be named *.bench.php.

The file must return a closure, or an array of closures. Each closure should take a parameter $multiplier which is how hard the test should be. The higher the $multiplier, the longer the test will take, by default it is 1. You should choose a reasonable number of iterations for your test (e.g. 1000) and multiply it by the $multiplier.

Example:

// mytest.bench.php

return function ($multiplier = 1) {
    $iterations = 1000 * $multiplier;
    for ($i = 0; $i < $iterations; ++$i) {
        // do something
    }
};

Or with multiple tests:

// mytest.bench.php

return [
    'my_test' => function ($multiplier = 1) {
        $iterations = 1000 * $multiplier;
        for ($i = 0; $i < $iterations; ++$i) {
            // do something
        }
    },
    'another_test' => function ($multiplier = 1) {
        $iterations = 1000 * $multiplier;
        for ($i = 0; $i < $iterations; ++$i) {
            // do something else
        }
    },
];
