Comment (by pramsey):

 In [changeset:"16393" 16393]:
 {{{
 #!CommitTicketReference repository="" revision="16393"
 Edge tree index on geometries makes distance calculations on large
 geometries
 go much faster. Needs to be used selectively and potentially with a
 caching
 component for maximum effect. Test it out using _ST_DistanceRectTree(geom,
 geom)
 for now.
