{{{django.core.handlers.profiler-hotshot}}} provides profiling support for Django when using mod_python. 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)
}}}

a 2nd option is [http://zilbo.com/@perfmon perfmon] which keeps track of performance data for individual requests and lets them be viewed via the django admin interface. This tool is free for people developing opensource projects.
