The Activity Stream on the Dashboard page for non-logged in users on http://fisheye.jboss.org takes a long time to create resulting in slow performance. The cause of this appears to be Lucene searches across the repositories for recent activity which makes the CPU spike to 100%.

To resolve this we should simply edit the relevant JSP to remove the Activity Stream from the Dashboard for non-logged in users (guests) and replace it with a Welcome image.
