Phalcon very slow using Phalcon\\Http\\Response();

问题:

I am experiencing a very strange issue with Phalcon.
Whenever I use Response inside a controller the framework becomes very slow. Here is my simple controller:

<?php  // file: app/controllers/TestController.php use Phalcon\Mvc\View;  class TestController extends ControllerBase {   private $response;   public function initialize()  {   $this->view->setRenderLevel(View::LEVEL_NO_RENDER);    $this->response = new Phalcon\Http\Response();   $this->response->setStatusCode(200, "OK");  }   public function indexAction()  {    $this->response->setContent("phalcon")->send(); // very slow  }  } 

Whenever I use new Phalcon\Http\Response(); Phalcon becomes very slow. For example testing it with:

ab -c 50 -n 100 ... 

Request/sec: 10

If I use a blank Controller I get

Request/sec: 1000+

The route is:

<?php //file: app/config/routes.php  $router = new \Phalcon\Mvc\Router(); $router->add("/:controller/:action", array("controller" => "test", "action" => "index")); 

I tested it on AWS:

c4.large PHP 5.5.9-1ubuntu4.6 (cli) (built: Feb 13 2015 19:17:11) 2 cpu - 3.75gb ram Apache/2.4.7 (Ubuntu) PHP/5.5.9-1ubuntu4.6 

We experienced the same behavior on a Macbook pro with osx 10.10.1

The problem is when I call the send() method on the response:

$this->response->send(); // slows down everything 

Note

As suggested by @Phate01 I tried return $response; instead of $response->send(); and it is still very slow

I went to this page: http://docs.phalconphp.com/en/latest/reference/response.html and they say that

If you are using the full MVC stack there is no need to create responses manually. However, if you need to return a response directly from a controller’s action follow this example:

<?php class FeedController extends Phalcon\Mvc\Controller {      public function getAction()     {         // Getting a response instance         $response = new \Phalcon\Http\Response();          $feed = //.. load here the feed          //Set the content of the response         $response->setContent($feed->asString());          //Return the response         return $response;     }  } ?> 

As you can see it return directly the Response object.

I guess that you should call the ->send() outside the controller, and also adding some headers would help
