LoadingElementDuration property is used to control the animaion duration of LoadingElement. The value for LoadingElementDuration property must be specified in milliseconds. By default, the LoadingElement fades in and fades out.

But I noticed that, irrespective of whatever duration you set, the LoadingElement was fading in and out at the same speed. I have done some research on google and came across the following stackoverflow article which explained the fix for the issue.

To fix the issue, we need to parse the duration to integer. Open "jquery.unobtrusive-ajax.js" and change the following line 
duration = element.getAttribute("data-ajax-loading-duration") || 0;
duration = parseInt(element.getAttribute("data-ajax-loading-duration")) || 0;

After you have made the change, reference "jquery.unobtrusive-ajax.js" file in the "Index" view
<script src="~/Scripts/jquery.unobtrusive-ajax.js" type="text/javascript"></script>

Finally set, LoadingElementDuration and test your application
@Ajax.ActionLink("All", "All"
    new AjaxOptions 
      HttpMethod = "GET"
      UpdateTargetId = "divStudents"
      InsertionMode = InsertionMode.Replace, 
      LoadingElementId = "divloading",
      OnBegin = "ClearResults",
      OnSuccess = "CountRows",
      LoadingElementDuration = 2000
