As detailed in the following link:
http://www.nabble.com/AppFuse-Spring-Security-AspectJ-issues-td17047478s2369.html

The same issue is confirmed using JSP. The signup page for appfuse takes about 5 seconds to load and it happened after reloading the page everytime. When the security.xml's pointcut expression is changed to the following, the first page take about the same time for the obvious reason (JSP compiling). However, the second page reload take only about 1 second (relative terms).

    <global-method-security>
        <protect-pointcut expression="execution(* *..service.UserManager.getUsers(..))" access="ROLE_ADMIN"/>
        <protect-pointcut expression="execution(* *..service.UserManager.removeUser(..))" access="ROLE_ADMIN"/>
    </global-method-security>
