if you use the Zend_View_Helper_Action for dispatching recursive the Pimcore_Controller_Action_Helper_ViewRenderer will re-add all template paths. Everytime pimcore try to include all the files. For example we had ~300 recursive calls, pimcore needs around 90 Seconds (i think around 300.000 includes) to deliver the page.

this pull request should fix this issue.

to reproduce

an Action:

 public function fooAction() {
  if(!$this->_getParam('inkr'))
   return die();

 $inkr = $this->_getParam('inkr');
 $this->view->inkr =  --$inkr;
}

and a view

   if($this->inkr)
      echo $this->action('foo', 'default', null, array('inkr' => $this->inkr));
