If you are optimising for speed, there is nothing wrong with only making 
1 catalog query, and then format the page from that. If possible.

That is basically what php base boards do anyway.

Also if the page is that dynamic, and you need that much speed, maybe 
you shouldn't use zpt very much. You could generate the most critical 
pages from pure Python.

That would allow for a whole different bag tricks, but still be nicer 
than php.

Like caching a generated view and then replacing it vith a python 
generated board view.

def re_cache(self)
     self.layout_cache = self.board_template(self, self.REQUEST)

def index_html(self):
      board_view = self.generate_board_view()
      return self.layout_cache.replace('%%board_view%%', board_view)
