title: Jenkins GUI only shown after waiting for 2 minutes
body: <p>My Jenkins version is Jenkins 1.508. Some googling around seemed to indicate that I needed a small change in my jenkins.xml (see for instance <a href="http://devophuman.blogspot.nl/2013/04/jenkins-is-going-wild.html" rel="noreferrer">http://devophuman.blogspot.nl/2013/04/jenkins-is-going-wild.html</a>), but that xml change did not help a lot in my case. Today I installed the monitoring plugin, and can see that jenkins needed 112,978 ms to respond to my request, where should I look for the culprit?</p>
