title: Why it's so slow when a wcf client connects to the service?
body: <p>I met a performance issue when using the WCF service.</p>
  
  <p>Here's the story: </p>
  
  <ol>
  <li><p>I wrote a self-hosted WCF service which is hosted by a console application;</p></li>
  <li><p>I wrote a simple client to consume the service;</p></li>
  <li><p>After the WCF service is running, it takes over 15 seconds for the client to create connection with the service.</p></li>
  </ol>
  
  <p>The WCF service is extremely simple just something like "Hello World". Is this normal?</p>
