title: Angular-cli: ng serve without optimisations
body: <p>I'm using the angular-cli and really like the features it comes with. I've just noticed that when <code>ng serve -dev</code> is run from the terminal, it outputs the following information about optimisation:</p>
  
  <pre><code>6ms module order optimization
  7ms module id optimization
  13ms chunk reviving
  10ms chunk order optimization
  46ms chunk id optimization
  </code></pre>
  
  <p>Is it possible to turn off these optimizations? My thoughts are that it could speed up the builds when running the development server.</p>
