title: Angular 4 CLI too slow after ng serve and when updating
body: <p>I have pasted a screenshot after i run ng serve. it is on 34946 ms. it is pretty slow and it is hurting the performance of our team. When we also update our code, it takes too long to reload the page. </p>

  <p>My version of angular is Angular CLI version (1.2.7)</p>
  
  <p>Is this an issue or is this normal in Angular CLI?</p>
  
  <p>We already have around 40 components on the project but i am not sure if it affects the loading performance.</p>
  
  <p>Here is the specs of my PC just incase. </p>
