Use django-devserver https://github.com/dcramer/django-devserver

I haven't worked with Django in a bit so my memory is foggy, but if settings.DEBUG is true, you should be able to do something like:

    from django.db import connection
    print len(connection.queries)

Put that in a middleware class's process_response() and it should print the query count for every request.

One option is to use the debug_toolbar package. You can set it up to display only when testing or only when an admin is logged in, and it will give you a convenient bar on the right side that shows exactly how long everything took, along with all SQL queries. This allowed me to greatly cut down the number of queries by judiciously using fetch_related.
