title: Using ext-all.js or ext.js for production?
body: <p>I saw in some ExtJs examples that they are only include <code>ext.js</code> in the page and ExtJs resolve all dependencies via XHR request after loading <code>app.js</code>, <em>Lazy load</em>. But I checked the debugger network and I found that ExtJs made <code>~250</code> XHR requests to resolve dependencies.</p>
  
  <p>Making ~250 requests for loading an application doesn't seems a good solution. <strong>I want to know</strong> should I use <code>ext.js</code> (Lazy loading) or <code>ext-all.js</code> (No more requests) for production version?</p>
