title: EC2 instance types's exact network performance?
body: <p>I cannot find exact network performance details for different EC2 instance types on Amazon. Instead, they are only saying:</p>
  
  <ul>
  <li>High</li>
  <li>Moderate</li>
  <li>Low</li>
  </ul>
  
  <p>What does this even mean? I especially want to know the exact amount of <code>Traffic-OUT</code> on each instance type.</p>
  
  <p>I need to do live streaming and my stream bit rate will be 240kbps. So I need to know which instance type can handle how many concurrent viewers.</p>
