I did some performance tests and confirmed your findings. I've created a ticket that includes a patch that changes the default geodetic distance calculation to use `ST_distance_sphere` instead: http://code.djangoproject.com/ticket/6715 My informal tests indicate that calculations are 30-40% faster, with a maximum of 0.25% loss in accuracy. I haven't committed yet because I wanted to solicit comments on the API that enables spheroid calculations. -Justin --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
