[Zope-dev] ape performance

Hi, I'm trying to use Ape for a photo album - the idea being that I just drop new photos where I normally do on the filesystem, and Zope provides a thumbnails-bells-and-whistles view onto it. Performance is extremely poor: viewing the root of the hierarchy causes *all* descendent objects to be loaded first (about 3000). Is there a way I can avoid or mitigate this problem? seb
