改进我的查询symfony

Question

您好我正在处理一个我有大量数据的项目。我有一个查询，它带来了超过30个非常糟糕的secondes，我希望有人可以帮助我改进它。

/////////////////////////////我的资料库// ////////////// //////////////

public function getr($id){
$q = $this->_em->createQuery("
SELECT r FROM AppBundle:R r JOIN AppBundle:C c WITH r.c_id IN  
   (SELECT ce FROM AppBundle:C ce JOIN AppBundle:Centre e 
   WITH ce.centre = :id) WHERE r.etat= 1");
$q->setParameter('id', $id);
return $q->getResult();

}

/////////////////////////////我的控制器// ////////////// //////////////

 public function filtercentreAction(Request $request){
$id = $request->get('filtercentre');
$em = $this->getDoctrine()->getManager();

if ($id) {
    $entities = $em->getRepository('AppBookingBundle:R')->getr($id);
}
return $this->container->get('templating')->renderResponse('r/show.html.twig', array(
    'entities' => $entities,
));

}
