> In version of SetCurrentIdentityFilter.java from eXo core 2.3.X (version used in GateIn and EPP) is ConversationState for anonymous user not created . But problem is that in eXo core 2.4.0-GA-SNAPSHOT is ConversationState always created even for anonymous user because of EXOJCR-779 . And this is causing performance problem in CacheUserProfileFilter.java :
> {code}
> if (state != null)
> {
>           if (state.getAttribute(USER_PROFILE) == null)
>           {
>              OrganizationService orgService =
>                 (OrganizationService)getContainer().getComponentInstanceOfType(OrganizationService.class);
>              begin(orgService);
>              User user = orgService.getUserHandler().findUserByName(state.getIdentity().getUserId());
>              end(orgService);
>              state.setAttribute(USER_PROFILE, user);
>           }
> }
> {code}
> When we are using eXo core 2.4.0, then ConversationState is never null, which means that the inner clausule is always called, which means expensive start of Hibernate transaction (And this is not good for performance). This is called for every HTTP request of anonymous user, because User is never found and so that statement: "state.getAttribute(USER_PROFILE) == null" is always true.
> Possible workaround can be use something like: 
> {code}
> if (state != null && !IdentityConstants.ANONIM.equals(state.getIdentity().getUserId()))
> {code}
> in CacheUserProfileFilter.java.
