title: Is using the completed type name in code is faster than a using directive for the whole namespace
body: <p>For the best website performance is using: (for example)</p>
  
  <pre><code>Telerik.Web.UI.RadChart ResultChart = new Telerik.Web.UI.RadChart();
  </code></pre>
  
  <p>Is faster than :</p>
  
  <pre><code>using Telerik.Web.UI;
  </code></pre>
  
  <p>and</p>
  
  <pre><code>RadChart ResultChart = new RadChart();
  </code></pre>
  
  <p>and what if i used the <code>using</code> directive in many modules in ASP.net page, does the compiler use it once?</p>
