title: angular 2 cli very slow on first serve and a while refresh
body: <p>After using in angular for awhile i decided to move to angular 2.
  I'm using the latest angular-cli version and latest node and npm.</p>
  
  <p>I have a not brand new pc but it suits me well.
  CPU: E7500
  RAM: 4GB
  Win7 64 bit</p>
  
  <p>So i open the webstorm, wait a few second for it to load everything and the i type "ng serve", this command took 22s!!!
  This is very slow, although this command took place only once, it's not so bad bat its is bad, right?</p>
  
  <p>The second problem is very annoying,
  after i change something in the code (html, css..) the refresh action took 7-8 second, this is nightmare for me and it's very frustrating!</p>
  
  <p>Now, i know that the cli project is done a lot for me and i know it can cost me in a few second but i simple cant work like this especially with the refresh action.</p>
  
  <ol>
  <li>Is this normal for cli or this is only because my pc?</li>
  <li>Is there something i can do to speed up the refresh action?</li>
  </ol>
  
  <p>Thanx</p>
