Summary

0000123: XAMPP PHP build executing slowly

Description

This report is in response to kleinweby in the forum topic XAMPP 1.0.1, slow PHP execution times <http://www.apachefriends.org/f/viewtopic.php?f=29&t=36481>. [^]

For some reason, the XAMPP PHP build is executing slowly. Here is a more thorough test and the results. XAMPP is performing almost twice as slow as the built in OSX build and MAMP. I'm not sure why the Linux build is twice as fast.

<code>
<?php
    $start = microtime(true);

    for ($i = 0; $i < 1E6; $i++) {
        hash('sha512', 'The quick brown fox jumped over the lazy dog.');
    }
    for ($j = 0; $j < 1E6; $j++) {
        $object = new StdClass();
        $object->sentence = 'The quick brown fox jumped over the lazy dog.';
    }
    for ($k = 0; $k < 1E6; $k++) {
        $lim = sqrt($k);
        for ($d = 2; $d <= $lim; $d++) {
            if ($k % $d == 0) {
                break;
            }
        }
    }

    echo ((microtime(true) - $start) * 1000).' ms'.PHP_EOL;
?>
