title: Ionic list about 100-150 elements very brake
body: <p>I have a list in an ionic-app with elements that contains a 20x20 px image on each. 
  The problem is that when number of elements reaches more than 50 it begins to insanely lag.</p>
  
  <p>Here is my code for the list:</p>
  
  <pre><code>&lt;ion-content has-bouncing="true"&gt;
    &lt;div class="item-wrapper" ng-repeat="user in users"&gt;
      &lt;div class="item item-avatar item-custom-avatar"
           ng-click="openProfile(user.ID)"
           on-tap="openProfile(user.ID)"&gt;
        &lt;h2&gt;{{ user.LAST_NAME + ' ' + user.NAME }}&lt;/h2&gt;
        &lt;p class="employees-work-position"&gt;{{ user.WORK_POSITION }}&lt;/p&gt;
      &lt;/div&gt;
    &lt;/div&gt;
  &lt;/ion-content&gt;
  </code></pre>
  
  <p>How could I fix it? Lagging occurs even when I use a single pre-saved image for the every cell.</p>
