title: long polling vs streaming for about 1 update/second
body: <p>is streaming a viable option?

  is one better than the other for this case?</p>
  
  <p>I am working on a GWT application with Tomcat running on the server end. To understand my needs, imagine updating the stock prices of several stocks concurrently.</p>
