django.core.handlers.profiler-hotshot provides profiling support for Django when using mod_python. Hotshot generates logs that can be also used by aplication like kcachegrind. Read Django profiling with hotshot and kcachegrind for more details.
Here's a similar solution for the internal development webserver. Apply the included patch to
django/core/management.py and start Django with
manage.py runserver. Each request will create a
.prof file in your
/tmp directory. You can then open a Python shell and print the statistics:
>>> import hotshot.stats >>> stats = hotshot.stats.load("stones.prof") >>> stats.strip_dirs() >>> stats.sort_stats('time', 'calls') >>> stats.print_stats(20)
You can also use gather_profile_stats.py in the Django distribution to aggregate the generated profilings and open them with pstats.Stats
Using WSGI to profile
An alternative approach is to run django from a boring WSGI server and profile that. For example using wsgiref you can create a really simple WSGI server for running django:
from wsgiref.simple_server import make_server from django.core.handlers.wsgi import WSGIHandler httpd = make_server('', 8000, WSGIHandler()) httpd.serve_forever()
Run this using:
$ DJANGO_SETTINGS_MODULE=mysite.settings python myserver.py
To profile this run using cProfile (or profile):
$ DJANGO_SETTINGS_MODULE=mysite.settings python -m cProfile myserver.py
The default invocation will print the profile stats when you kill the server, it's probably more useful to write to a file and use pstats to read it:
$ DJANGO_SETTINGS_MODULE=mysite.settings python -m cProfile -o mysite.profile myserver.py ... lots of requests ... $ python >>> import pstats >>> s = pstats.Stats("mysite.profile") >>> s.sort_stats("time").print_stats(20)
