The PerformanceMonitor extension profiles the work of PHP functions and methods on your server. These "profiles" (i.e. logfiles) are stored as Json-Trees in the file system. After profiling you can use the Special Page Special:PerformanceMonitor to visualise the results as diagrams. The diagrams allow drilling down to more detailed levels and show you, whatever the server does all the time you are waiting for it.

Technically the extension uses a JavaScript library called InfoVis for visualisation, which you have to download separately and put it inside the extension folder.

Download

Download PerformanceMonitor

The code of this extension is available for download on GitHub. Put it into the folder /extensions/PerformanceMonitor.

Download the InfoVis Toolkit

Download the InfoVis Toolkit from http://philogb.github.io/jit/downloads/Jit-2.0.1.zip and put it inside the /extensions/PerformanceMonitor/js-includes/jit-2.0.1 folder of the extension.

Download Bootstrap Library

Download the Bootstrap Library from http://getbootstrap.com/getting-started/ and put it inside the /extensions/PerformanceMonitor/js-includes/bootstrap-3.1.1-dist folder of the extension.

Instalacja

LocalSettings.php

$wgLanguageCode = 'en'; // other languages untested

// the following were my settings during development,
// you probably do not need all of it...:

error_reporting( 1 );
ini_set( 'display_errors', 1 );

$wgDebugLogFile = '$IP/DebugLogFile.log';
// myWiki/DebugLogFile.log must exist and have the server must have write access

$wgShowDBErrorBacktrace = true;

$wgRawHtml = true;
$wgAllowUserJS = true;

$wgResourceLoaderDebug = false; // Debug javascript: $wgResourceLoaderDebug = true;

// include the Extension:
require_once( "$IP/extensions/PerformanceMonitor/PerformanceMonitor.php" );
// PerformanceMonitor: Don't forget to adapt StartProfiler.php!!!
$egPerformanceMonitorServerName = "Propellerbook"; // whatever is the name of your server
$egPerformanceMonitorExtensionPath = "/Applications/MAMP/htdocs/mediawiki-1.20.8/extensions/PerformanceMonitor/";
$egPerformanceMonitorLogfilesPath = "/Applications/MAMP/htdocs/mediawiki-1.20.8/logs/autologs/"; // make sure to configure this folder writable your server

use /index.php5/Main_Page

$wgScriptPath       = "";
$wgScriptExtension  = ".php5";

instead of /wiki/Main_Page

$wgScriptPath       = "";
$wgScriptExtension  = ".php5";
$wgArticlePath      = "/wiki/$1";
$wgUsePathInfo      = true; // Enable use of pretty URLs

StartProfiler.php

The file StartProfiler.php is located (if it exists) in the main folder of the wiki, i.e. the same as LocalSettings.php. If it exists, comment out the current code and add the following code. Otherwise create it and put the following inside:

<?php
require_once( dirname(__FILE__).'/includes/profiler/ProfilerSimple.php' );
$monitorPath = "/Applications/MAMP/htdocs/mediawiki-1.20.8/extensions/PerformanceMonitor/";
require_once( $monitorPath . "ProfilerSimpleJson.php" );
$wgProfiler['class'] = 'ProfilerSimpleJson';

ProfilerSimple.php

We found that ProfilerSimple.php has been removed in one of the last MediaWiki releases, when "MediaWiki 1.25 profiling was completely rewritten" (see Manual:Profiling ). You can find the old file from back then (should be MW 1.20), that used to be shipped in /includes/profiler/ProfilerSimple.php - it was only used to derive a profiler from it, that creates a json file instead of the normal line-by-line protocol. Feel free to adapt this for newer versions of MediaWiki...
