Phalcon使用Phalcon \ Http \ Response()非常慢. [英] Phalcon very slow using Phalcon\Http\Response();

问题描述

我在使用Phalcon时遇到一个非常奇怪的问题.
每当我在控制器内使用Response时，框架就会变得非常慢. 这是我的简单控制器:

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
 }

}

每当我使用new Phalcon\Http\Response();时，Phalcon就会变得非常缓慢.例如，使用以下命令进行测试:

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

ab -c 50 -n 100 ...

请求/秒: 10

如果我使用空白控制器，则会得到

If I use a blank Controller I get

请求/秒: 1000 +

路线为:

<?php
//file: app/config/routes.php

$router = new \Phalcon\Mvc\Router();
$router->add("/:controller/:action", array("controller" => "test", "action" => "index"));

我在AWS上对其进行了测试:

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

我们在使用osx 10.10.1的Macbook pro上遇到了相同的行为

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

问题是当我在响应上调用send()方法时:

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

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

注意

如@ Phate01所建议，我尝试使用return $response;而不是$response->send();，但它仍然很慢

Note

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

推荐答案

我转到了此页面: http://docs.phalconphp.com/en/latest/reference/response.html 他们说

如果您使用完整的MVC堆栈，则无需手动创建响应.但是，如果您需要直接通过控制器的操作返回响应，请遵循以下示例:

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;
    }

}
?>

如您所见，它直接返回Response对象.

As you can see it return directly the Response object.

我想您应该在控制器外部调用->send()，并且添加一些标头会有所帮助

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