title: Performance boost needed - app users fanpage likes check
body: <p>I have performance issues with my facebook app.</p>
  
  <p>I need to check, if app users friends like an fanpage. But problem is: time.</p>
  
  <p>One query to graph /fanpage_id/members/userId needs ~200ms (my test user have 4 friends, time was 977ms). Customer want at last one check per 24hours(app cache remove event on global.asax works well) for all users BUT.. lets say 500 users and every user have 500 friends * 200ms .. its a lot of time and queries to facebook graph.</p>
  
  <p>Any ideas how improve it ?</p>
