title: Sencha Touch ResumeEvents is a catastrophe
body: <p>I'm using Sencha's Ext.data.Store to hold some items.  Right now they come from an xml webservice but that will change to a JSON query.  After adding 500 items calling ResumeEvents on the Store can take 20 seconds!  If I comment the Suspend and ResumeEvents from my code it runs faster.  </p>
  
  <p>What gives?  Does the library not combine multiple event notifications, or does is save all of them to send when you call ResumeEvents?</p>
  
  <p>This is not good.</p>
  
  <p>Thanks,
  Gerry</p>
