title: HybridRelations laravel mongo is really slow
body: <p>Used HybridRelations to store user notifications in mongoDB instead of mysql and imported 3million records and now user-&gt;notifications()-&gt;take(5)-&gt;get() or user-&gt;notifications()-&gt;paginate(5) takes over 30 seconds.
  any idea how to speed it up?
  on mysql with same amount of records it took 200 milliseconds.</p>
  <p>notificaiton model has user_id and description and priority and read flag and user_id is set as an index.</p>
