I use ZendFramework2 and Doctrine for launching my project. My CPU shows high usage on `httpd` requests. I enabled `opcache` for filecaching, and `memcache` for Doctrine.

Any idea why it might have a load average being near 5.0? I put `die('test1')` inside of `onBootstrap` of ZendFramework2 one time, and another time I put `die('test')` before.

```
die('test2')
Zend\Mvc\Application::init(require 'config/application.config.php')->run();

```

My Apache bench shows that when the framework is loaded without any connection to a database or goes to any controller it's 5x slower. Why is zf2 acting like this and what might be a possible solution to normalize it's behavior?

**[question update]**

I profiled with Xdebug And Webgrind and found out processes like on bootstrap take high percentage

on bootstrap I have this line of codes

```
        //...
        $eventManager->attach(MvcEvent::EVENT_ROUTE, function($e) use ($blacklistForNormalUser, $auth) {
        $match = $e->getRouteMatch();

        // No route match, this is a 404
        if (!$match instanceof RouteMatch) {

            return;
        }

        // Route is whitelisted
        $name = $match->getMatchedRouteName();

        if (!in_array($name, $blacklistForNormalUser)  ) {
            return;
        }

        // User is authenticated
        if ($auth->hasIdentity() ) {
            return;
        }

        // Redirect to the user login page, as an example
        $router   = $e->getRouter();

        if(in_array($name, $blacklistForNormalUser)){

            $url      = $router->assemble(array(), array(
                'name' => 'user/login'
            ));

        }

        $response = $e->getResponse();
        $response->getHeaders()->addHeaderLine('Location', $url);
        $response->setStatusCode(302);

        return $response;
    }, -100);
    //...

```

another high point is
