Re: My App is Getting too Slow
Ok thanks AD, here is what I got from the Profiler I still can't
understand which part to investigate and what eats up all the
resources here:
http://www.eg-host.net/cache_grind_requests_controller.zip
Sorry for pasting the Model relations the way I did... thought this
will be less confusing as Model Names will never affect the speed.
Anyway the Request Model has the following relations:
var $hasOne = array("DraftMessage");
var $hasMany =
array("TourFile","RequestsMeal","RequestsCruise","RequestPayment","RequestsHotel","RequestsThingstodo","RequestReminder","RequestsGroupMember","RequestsDomesticFlight","RequestsTransfer","RequestsInternationalFlight","RequestsTrainTicket","RequestRefusal","RequestReply"=>array("order"=>"RequestReply.id
asc"));
var $belongsTo = array(
'Department', 'Branch', 'Client',
'RequestStatus', 'Currency',
'Source' => array(
'className' => 'Source',
'foreignKey' => 'source_id'
),
'SubSource' => array(
'className' => 'Source',
'foreignKey' => 'sub_source_id'),
'Staff' => array(
'className' => 'Staff',
'foreignKey' => 'staff_id'),
'DelegatedTo' => array(
'className' => 'Staff',
'foreignKey' => 'delegated_to'));
It is important to say that the system is not only slow at this
controller... I am just maintaining the same example request
throughout the discussion. The whole system is heavy, although non-db
dependent ones work bit faster.

One of the things it does is prevent loops by imposing a max nesting level. http://xdebug.org/docs/basic Although hitting this limit (immediately) most likely hints at part of the cause of your problems - why don't you just increase the limit (to say 200) so you can get a profile - since your app "worked" before you obviously don't have an infinite loop in your code - you've simply got a very-nested loop in your code. And are currently getting distracted by a relevant - but not immediately so - detail. Hower, here's what you stack trace tells me: > 2 4.7698 3677016 Dispatcher->dispatch( ) ..\index.php:88 It took 4.7 seconds to get to line 88 of index.php. http://github.com/cakephp/cakephp1x/blob/master/app/webroot/index.php#L88 That's ALOT of time - and isn't dependent on your app code. it means you have some kind of setup problem. > 89 8.6338 11936400Model->schema( ) ..\model.php:753 It took a further 4 seconds before not-completing instantiating your model network.

No, the models are all connected when the app is instanciated,
containable only affects things when you're querying the database.
Remove some associations to see if that fixes it. If it does, rethink
you're data model or look into the lazy loading behaviour.
Cheers,
Jon

Re: My App is Getting too Slow
Hey Jon...
Actually I am running this on a windows server so the folders should
be writable with no problems.
I only have the Containable Behavior on all the models (AppModel) and
Tree in both ARO and ACO (ACL) models. I believe this is not a
problem.
Here below is an example of the associated models to the this
controller's main model.
var $hasOne = array("MODEL");
var $hasMany =
array("MODEL","MODEL","MODEL","MODEL","MODEL","MODEL","MODEL","MODEL","MODEL","MODEL","MODEL","MODEL","MODEL","MODEL"=>array("order"=>"MODEL.created
ASC"));
var $belongsTo = array(
'MODEL', MODEL', 'MODEL', 'MODEL', 'MODEL',
'Source' => array(
'className' => 'Source',
'foreignKey' => 'source_id'
),
'SubSource' => array(
'className' => 'Source',
'foreignKey' => 'sub_source_id'
),
'Staff' => array(
'className' => 'Staff',
'foreignKey' => 'staff_id'
),
'DelegatedTo' => array(
'className' => 'Staff',
'foreignKey' => 'delegated_to'
) );
So as you can see there a a number of few models attached. And I am
still expecting this to increase... but this shouldn't be a problem
too cuz I am using containable

Re: My App is Getting too Slow
Have you profiled the request yet? (Suggested above.) Look into xdebug - specifically http://xdebug.org/docs/profiler. btw. Are you absolutely sure it's server time you're waiting on? Yslow or Pagespeed will tell you that. Hmm... 79 queries is absolutely nuts too. I've heard it said - can't remember where - that anything over about 7ish per request is asking for trouble. (General rule of thumb.)

The sql execution time for Ayman is 79ms, the page loads in 10s (apparently) - it's very obvious the queries themselves aren't the problem. It takes at most an hour from "what's profiling?" to using xdebug (or at the very least debug kit's awesome timers) to be able to see exacty where your php time is going.

Well thanks for your help... Actually all 79 queries are made on the same database that runs on the same machine.

Re: My App is Getting too Slow
79 queries into a single database? You see, there's this design flaw in CakePHP, in which it connects into database as soon as the controller is instantiated. I am not sure about other database drivers, BUT, in Mysql's, i.e. if you have 4 databases schemas, and you happen to use 4 models in a single controller, each model connecting into a different database schema, you'll end up having 4 database connections for _each_ request you got in this controller - either you use the model object or not. 4 connections to 4 database schemas, even if they're in the same machine. Also take a look into the I/O resource used to connect into the database, which turns out to be a bottleneck point. If webserver and database are within the same host, consider using unix socket instead TCP/IP connections, it'll help to reduce connection latency. In my previous experience with such performance issues regarding DB, I solved this problem of yours when I've hidden CakePHP of the application. I mean, dinamically generating static pages with CakePHP...

Even if each of those queries took 0ms (and returned nothing) it'll cost you approximately 2ms per query - which is not insignificant. Of course, if 78 of those queries are describes, and there's only 1 'real' query you don't need to worry about them. > the pages takes about 8 to 10 > seconds to load.

Install debug kit ( http://github.com/cakephp/debug_kit ) and look at the timer tab to get a broad idea of where most of your time goes set debug to 0 to get more accurate timer info. AND set debug to 0 and profile (http://xdebug.org/docs/profiler + e.g. http://code.google.com/p/webgrind/) to see /exactly/ into which functions your time is going. Do not profile with debug > 0 as what you'll get will be inaccurate to the point of pointless. Use the results to know where to focus your efforts. Bear in mind that if it's slow only because of some debug > 0 process you may not need to do anything. hth, AD Check out the new CakePHP Questions site http://cakeqs.org and help others with their CakePHP related questions.

Other script running on the same server are performing well, even empty pages on this same application is still loading good with all the App Controller functions running. Yet it is too slow in querying pages even if the autoRender is set to false. so it has nothing to do with the HTML and Images !! :( I thought it's with the mobile device detection I had there but that runs in the App Controller beforeFilter() function so it should be running on empty pages too !!! Is there a way i can debug that parts that makes all this delay ?! Check out the new CakePHP Questions site http://cakeqs.org and help others with their CakePHP related questions.
