title: Django persistent database connection
body: <p>I'm using django with apache and mod_wsgi and PostgreSQL (all on same host), and I need to handle a lot of simple dynamic page requests (hundreds per second). I faced with problem that the bottleneck is that a django don't have persistent database connection and reconnects on each requests (that takes near 5ms).
  While doing a benchmark I got that with persistent connection I can handle near 500 r/s while without I get only 50 r/s.</p>
  <p>Anyone have any advice? How can I modify Django to use a persistent connection or speed up the connection from Python to DB?</p>
