django-cprofile-middleware

This is a simple profiling middleware for Django applications. I wrote it because I got tired of printing "start" "stop" "stop 2" in my programs to find the bottlenecks.

I found a simple example on @dcramer's slideshare and modified it to support sorting.

Installing

$ pip install django-cprofile-middleware

Then add django_cprofile_middleware.middleware.ProfilerMiddleware to the end your MIDDLEWARE in settings.py. This option was called MIDDLEWARE_CLASSES in versions of Django before 1.10.

For example:

MIDDLEWARE_CLASSES = (
    'django.middleware.common.CommonMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'startup.do.work.FindProductMarketFitMiddleware',
    ...
    'django_cprofile_middleware.middleware.ProfilerMiddleware'
)

Running & Sorting Results

Once you've installed it, log in as a user who has staff privileges and add ?prof to any URL to see the profiler's stats. For example to see profile stats for http://localhost:8000/foo/, visit http://localhost:8000/foo/?prof.

You can also pass some options:

count: The number of results you'd like to see. Default is 100.

sort: The field you'd like to sort results by. Default is time. For all the options you can pass, see the docs for pstats.

download: Download profile file, that can be visualized in multiple viewers, e.g. SnakeViz or RunSnakeRun

Enjoy!
