Phalcon 在我使用 HttpResponse::send 时非常慢

我构建了一个Micro应用程序，一切正常。但性能测试显示出令人沮丧的结果。应用程序非常慢：

ab -n 1000 -c 50 http://myproject.net/

正常结果：

Concurrency Level:      100
Time taken for tests:   58.083 seconds
Complete requests:      1000
Failed requests:        0
Non-2xx responses:      1000
Total transferred:      578000 bytes
HTML transferred:       189000 bytes
Requests per second:    17.22 [#/sec] (mean)
Time per request:       5808.272 [ms] (mean)
Time per request:       58.083 [ms] (mean, across all concurrent requests)
Transfer rate:          9.72 [Kbytes/sec] received

在我评论$response->send（）之后;测试结果变得更好：

Concurrency Level:      100
Time taken for tests:   7.960 seconds
Complete requests:      1000
Failed requests:        0
Total transferred:      166000 bytes
HTML transferred:       0 bytes
Requests per second:    125.62 [#/sec] (mean)
Time per request:       796.048 [ms] (mean)
Time per request:       7.960 [ms] (mean, across all concurrent requests)
Transfer rate:          20.36 [Kbytes/sec] received

在索引文件中，我将响应对象定义为共享服务：

$di->setShared(System::RESPONSE, new App'Http'Response());

App''Http''Response

是一个扩展 ''Phalcon''Http''Response 的类，允许我添加应用程序中所需的一些标头

namespace App'Http;
class Response extends 'Phalcon'Http'Response
{
    public function getDefaultErrorMessages()
    {
        return $this->defaultErrorMessages;
    }
    public function setDefaultErrorMessages($messages)
    {
        $this->defaultErrorMessages = $messages;
    }
    public function setErrors(array $messages)
    {
       $this->validationErrors = $messages;
    }
    public function setErrorContent('Exception $e, $developerInfo = false)
    {
        $errorCode = $e->getCode();
        $statusCode = 500;
        $message = 'Unspecified error';
        $error = [];
        if ($this->validationErrors) {
            $error['errors'] = $this->validationErrors;
        }

        $this->setJsonContent(['error' => $error]);
        $this->setStatusCode($statusCode);
    }

    public function setJsonContent($content, $jsonOptions = 0, $depth = 512)
    {
        parent::setJsonContent($content, $jsonOptions, $depth);
        $this->setHeader('Access-Control-Allow-Origin', '*');
        $this->setHeader('Access-Control-Allow-Methods', 'GET,PUT,POST,DELETE');
        $this->setHeader(
            'Access-Control-Allow-Headers',
            'Content-Type, X-Requested-With, X-Authorization'
        );
        $this->setContentType('application/json');
    }
}

我的所有代码都包装在索引文件中的 try-catch 语句中。我试图犯一个错误来抛出一个异常，如果异常是由 Zephir 抛出的，测试显示快速的结果，而如果它是由我们的代码抛出的，测试显示同样缓慢的结果。

当我使用"ab"的-k修饰符时，结果会变得更好：

ab -k -n 1000 -c 50 http://myproject.net/

    public function registerServices($di)
    {
        // ....
        $di->getView()->disable();
    }

<?php
namespace Application'Api'Controllers;
use 'Phalcon'Mvc'Controller;
class ControllerBase extends Controller {
    /**
     * Captures method result and tries to make a JSON response out of it.
     * 
     * @param 'Phalcon'Mvc'Dispatcher $dispatcher
     * @return 'Phalcon'Http'Response
     */
    protected function afterExecuteRoute($dispatcher) {
        $content = $dispatcher->getReturnedValue();
        // some logic for prematurely generated content (debugs/warnings)
        // ...
        if(is_object($content)) {
            if(is_callable(array($content, 'toArray'))) {
                $content = $content->toArray();
            } else {
                $content = (array) $content;
            }
        }

        $this->response->setContentType('application/json', 'UTF-8');
        $this->response->setJsonContent($frame);
        return $this->response->send();
    }
}

        // from previous code frame
        $this->response->setJsonContent($frame);
        return $this->response; // no send() here
    }
}

echo $application->handle() // returning instance of Response
         ->getContent(); // getting content to echo
