A good place to start is using django-debug-toolbar and taking a look at the queries generated for each view, so that you know what's taking long. There are tools for monitoring database performance, but I have no experience with them, so I'll leave it to other members in this list to make the recomendations. Maybe go after disk read/write monitoring if you have access to that?
When possible, moving the big functions in your code to asynchronous celery tasks [1] will nearly always speed things up. If you're doing big (hundreds of thousands of rows) db calls, try using DSE [2] [1] http://readthedocs.org/docs/django-celery/en/latest/ [2] http://pypi.python.org/pypi/dse Cheers, AT On Wed, Oct 12, 2011 at 10:19 AM, < [email protected]> wrote: > ** > > The django application I am working on is very slow on the server-side, and > I want to know why. > The essence is to identify which code-parts of processing one request take > most time. > > The app runs with mod_wsgi on Apache, here is what I tried: > > - django-timelog: the information logged is too unspecific and > high-leveled.
