title: Apple Push Notification -- is it possible to make a batch request for a large number of notifications?
body: <p>I need to push notification to 10,000 users. Do I need to make 10,000 requests to the Apple APNS server ? Could I do it in a batch way ?</p>
  
  <p>If I need to send the push requests one by one, is there any significant time difference between the first user and the last user when they receive the notification ?</p>
  
  <p>Thanks</p>
