title: Simulating high latency / intermittent network connections
body: <p>I'm load testing a network application using <a href="http://grinder.sourceforge.net/" rel="noreferrer">The Grinder</a> (on a Windows PC) and I wish to simulate imperfect network conditions in order to see what effect is has on the application load, in particular I'd like to see the effect of:</p>
  
  <ul>
  <li><strong>Variable network latency</strong>, so not only do different clients have different latency, but also latency may vary during the test for a single client.</li>
  <li><strong>Dropped network connections</strong> - I wish to simulate what happens when a network connection is abruptly / randomly dropped.</li>
  </ul>
  
  <p>What's the easiest way of doing this?</p>
