title: First time I navigate to Panorama Page it gets too long to load
body: <p>I'm developing a Windows Phone 7.1 application which has a panorama page.</p>
  
  <p>This panorama page has two panorama items one with two textblock and the other one with a bing map control. And I also set a 1,5MB image as panorama control background.</p>
  
  <p>This is Panorama's XAML:</p>

      &lt;!--Panorama-based applications should not show an ApplicationBar--&gt;

  <p>First time I navigate to panorama page I gets too long to show, and if I tap on back button and I come back to it, it loads more quickly.</p>
  
  <p><strong>How can I make to panorama's page loads faster?</strong></p>
