StopWatch

See http://blogs.msdn.com/b/webdev/archive/2014/07/29/profile-and-time-your-asp-net-mvc-app-all-the-way-to-azure.aspx for more info.

To register this filter you need to add the following line to the App_Start\FilterConfig.cs file:

filters.Add(new UseStopwatchAttribute());

For Example:

 public class FilterConfig
{
    public static void RegisterGlobalFilters(GlobalFilterCollection filters)
    {
        filters.Add(new HandleErrorAttribute());
        filters.Add(new UseStopwatchAttribute());  // Add this line
    }
}

Alternatively, to get the timings on specific controllers, add the [UseStopwatch] attribute to the controller. For example:

[UseStopwatch] public class HomeController : Controller

  <add key="TraceErrorTime" value="2.5" />
  <add key="TraceWarningTime" value=".5" />
  <add key="TraceInformationTime" value=".25" />
  <add key="SkipTimeInLayout" value="1" />

To see the time in each page, add the following code to the Views\Shared_Layout.cshtml file:

@Html.Encode(ViewBag.elapsedTime)
