In Ember, AJAX callback should it be wrapped in Ember run loop?

The below statement is from ember guides,

The most common case for using the run loop is integrating with a non-Ember API that includes some sort of asynchronous callback. For example:

DOM update and event callbacks
setTimeout and setInterval callbacks
postMessage and messageChannel event handlers
AJAX callbacks
Websocket callbacks

I usually will do for AJAX request,

Ember.$.ajax(
{
 type: "POST",
 url:"someurl",
 contentType: "application/json",
 success: function(data) {
 //Should I wrap this success callback code in Run loop. or is it safe to leave
 //Here I will set properties to display, I might call sendAction/send to communicate with parent.
 }
})

I haven't faced any problem with that but sometime rendering is taking too much time after I change data in callback ?. does any one face that issue ?

Should I use ember-ajax addon to wrap success callback in Ember run loop?.

PS: Below is from ember guides, you should wrap any non-Ember async callbacks in Ember.run. If you don't, Ember will try to approximate a beginning and end for you. Relying on autoruns is not a rigorous or efficient way to use the run loop.
