title: Comparison of JBoss AS 7.x and Glassfish 3.x?
body: <p>I was wondering if there is a (mostly) objective comparison between the <code>JBoss AS 7</code> and <code>Glassfish 3.x</code>?</p>
  
  <p>I don't care for any differences in standards or their implementation, I was thinking more about <em>startup time, failover, scalability, performance, memory footprint, known problems, administration, security, clustering</em> etc.</p>
  
  <p><strong>Real world examples &amp; experiences are very welcome!</strong></p>
