XSP are by default NOT cacheable. I wasn't aware of the fact that the
util logicsheet has a cacheable element. I've made a caching logicsheet
some weeks ago (need to search it again) but not tested very well but we
can give it a try. So, I'll commit that logicsheet into the repo very
soon and let you play with it.
