Calls to (for example!)

https://community.jboss.org/people/pmuir/avatar/23.png

are performed on every page load of www.jboss.org for a logged in user (and likely other systems). You can see an example of the performance at http://tools.pingdom.com/fpt/#!/c5qJlJ/https://community.jboss.org/people/pmuir/avatar/23.png

This is the second slowest call in the loading of www.jboss.org page by some margin. Additionally, before we can make the call, we must hit logininfo as well (see ORG-2193)

The situation is not much better with a warm cache - the time to get a 304 Not Modified is > 200ms
