Django persistent database connection

HardQuestions picture HardQuestions · Jul 14, 2009 · Viewed 37.6k times · Source

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.

Anyone have any advice? How to modify django to use persistent connection? Or speed up connection from python to DB

Thanks in advance.

Django 1.6 has added persistent connections support (link to doc for latest stable Django ):

Persistent connections avoid the overhead of re-establishing a connection to the database in each request. They’re controlled by the CONN_MAX_AGE parameter which defines the maximum lifetime of a connection. It can be set independently for each database.
