InstaBench

A simple benchmark class that compares function calls to each other, using the first function as baseline. The result is presented in msecs and a webkit-style "N times faster/slower" fashion.

This library requires PHP 4.3.0 or greater. It is licensed under a 2 clause BSD license. Fork away!

Using InstaBench

Simple example that compares a couple of serialization options in PHP:

$data = array(1,2,3,4,5,6,7,8,9,0 => array(1,2,3,4,5,6,7,8,9));

$benchmark = new InstaBench();

$benchmark->add("serialize", array($data));
$benchmark->add("var_export", array($data, true));

$benchmark->run();
$benchmark->results();

Example output

Here's an example from running the bundled test.php on a test setup:

% instabench # php test.php
InstaBench 0.1 (PHP 5.2.13-pl0-gentoo)
