title: Express / Node.js / WebStorm debugging is very slow
body: <p>I am trying to customize Node.js based web application: <a href="https://github.com/Mailtrain-org/mailtrain" rel="nofollow noreferrer">https://github.com/Mailtrain-org/mailtrain</a></p>
  
  <p>I want to do debugging. I did some configuration for launching the app
   as you can see config in the following image:</p>
  
  <p><a href="https://i.stack.imgur.com/6uK1l.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/6uK1l.png" alt="enter image description here"></a></p>
  
  <p>But debugging is not working and its very slow to start. It take 5 min to start debugging. </p>
  
  <pre><code>/Users/Calm/.nvm/versions/node/v7.0.0/bin/node --debug-brk=50039

  </code></pre>
  
  <p>Although it says port is already in using, but I didn't start any other debug process.</p>
  
  <p>Would you like to help me to make this work?</p>
