I have some which doesn\'t really do much, still it does really take the longest time to load. I have written the code down for you all to see:
app.js
This delay is the time angular library gets to parse your HTML. You can use ng-bind instead:
ng-bind
<div id="item" ng-controller="ItemController as item" ng-bind="item.simple"> </div>
This way, your page won't get polluted while angular loads its content.
