UpdateCase gives you the ability to setup a optimization engine to hunt down where the slow downs exist in your application. 
-> Then systematically you can work through and speed up these functions
-> You will then have a efficient application
-> This keeps results in a database so you can later review how your system runs even when you are not testing

# 1 > Usage

To use the optimization place a few calls which will idenity how much time elapses between. 
-> This will allow you to narrow down where there are slow downs in your code

$this->optimizationAddNote('Before find function');

# 2 > AppController

Place these 3 functions in your AppController

    private function optimizationStart() {
$this->Session->write('optimization_time_start', microtime(true));
$this->Session->write('optimization_notes', ''); //first empty it

//new method
$_SESSION['optimization_time_start'] = microtime(true);
$_SESSION['optimization_notes'] = '';
$file = APP.'tmp'.DS.'logs'.DS.'optimization';

$this->writeToLog('optimization', 'Starting');

public function optimizationAddNote($newNote) {

if (!isset($optObj)) {
$optObj = ClassRegistry::init('Optimization', 'Model');



private function setPageNameToView() {

$page = '';
$div = '_';

if (isset($this->params->params['prefix'])) {
$page .= $this->params->params['prefix'].$div;
if (isset($this->params->params['controller'])) {
$page .= $this->params->params['controller'].$div;
if (isset($this->params->params['action'])) {
$page .= $this->params->params['action'].$div;

if (isset($this->params->params['named'])) {
$page .= implode('_', $this->params->params['named']).$div;
if (isset($this->params->params['pass'])) {
$page .= implode('_', $this->params->params['pass']).$div;


function beforeFilter() {

$this->optimizationAddNote('Start'); //place these to test specific locations

# 3 > Place at END of LAYOUT

At the end of your layout (app/View/Layout/default.ctp) place this code
-> This is the last place to run so it is our end point

//let's log our api calls
$optimizationObj = ClassRegistry::init('Optimization', 'Model');
$res = $optimizationObj->addToLog(
(microtime(true) - $_SESSION['optimization_time_start']),

# 4 > Create DB

Create the 'optimizations' database using the following SQL

CREATE TABLE IF NOT EXISTS `test_updateCase`.`optimization` ( `id` INT NOT NULL AUTO_INCREMENT , `user_id` INT NOT NULL , `customer_id` INT NOT NULL , `page` VARCHAR(1000) NOT NULL , `datetime` DATETIME NOT NULL , `loadtime` DECIMAL(10,5) NOT NULL , `info` TEXT NOT NULL, `created` DATETIME NOT NULL , `modified` DATETIME NOT NULL,  PRIMARY KEY (`id`)) ENGINE = InnoDB;

# 5 > Add function
Create this function in the Optimization (model) app/Models/Optimization.php

function addToLog($user_id, $customer_id, $pageName, $loadTime, $info) {
$model = 'Optimization';
$this->data[$model]['id'] = NULL;
$this->data[$model]['user_id'] = $user_id;
$this->data[$model]['datetime'] = date('Y-m-d H:i:s');
$this->data[$model]['customer_id'] = $customer_id;
$this->data[$model]['page'] = $pageName;
$this->data[$model]['loadtime'] = $loadTime;
$this->data[$model]['info'] = $info;

if ($this->save($this->data)) {
return true;
} else {
die ('cannot save optimization');

function addNote($newNote, $limitToEvery = false)

if ($limitToEvery) {

if ($this->count > $limitToEvery) {
$this->count = 0;
//we hit our max, so we will now take some notes
} else {
//$newNote = 'skipping';
//return false; //skip until we hit our max

//$note = $this->Session->read('optimization_notes');
$note = $_SESSION['optimization_notes'];
if (!empty($note)) {
$note .= "<br/>\n";
//$note .= number_format(microtime(true) - $this->Session->read('optimization_time_start'), 3).': ';
$note .= number_format(microtime(true) - $_SESSION['optimization_time_start'], 3) . ': ';
$note .= $newNote;
//$this->Session->write('optimization_notes', $note); //first empty it
$_SESSION['optimization_notes'] = $note; //first empty it

$this->writeToLog('optimization', $note);



# 6 > Database changes

First logon to MYSQL and run the following commands


/Applications/MAMP/Library/bin/mysql --host=localhost -ulocal -ppassword


mysql --host=localhost -ulocal -ppassword

While your slow code is running - run this command a few times to see which db connections are slow

show full processlist \G;

Verify your indexes between database tables


If you want to create NEW indexes

ALTER TABLE `revisions` ADD INDEX( `phase_id`);

OR Create composite indexes
-> Look at all the conditions and where you have multiple calls you need to create composits for this
-> EG: if you have the following conditions

$conditions = array('AND' => array(
array('Revision.phase_id' => $phase_id),
array('Revision.element_id' => $element_id)

You need to create the index in MYSQL:

ALTER TABLE `revisions` ADD INDEX( `phase_id`, `element_id`);


If you need to remove an index

DROP INDEX `nameOfIndex` ON `tableName`;


# 7 > Cakephp DEBUG

Install CakePHP debug mode
-> View SQL log
-> This will display how long each DB call has took

Modify the indexes per the result to speed up the system.
