Pull request is open:

So, from PostgreSQL you can get raw GeoJSON. So there is no use in
parsing it first in Django into Python, and then serializing it again.
To speed up GeoJSON REST API, I patched ujson so that it can read
GeoJSON fields directly from PostgreSQL and then just dump it into REST
output. So no expensive GDAL conversions are needed.

We have all that already working in datastream based on MongoDB. Maybe
you should try it out. :-) And it supports not just numeric values, but
also nominal and graph:

The reason is because we want a time-series of network topology through
time. :-)
