WSGIProfile 0.1dev

First install WSGIProfile. You may also need to install the python-profiler package if you are on Ubuntu.

easy_install WSGIProfile
sudo apt-get install python-profiler

Next lets create a very simple WSGI application with one slow function:

import time

def app(environ, start_response):
    time.sleep(2)
    start_response('200 OK', [('Content-Type', 'text/html')])
    return ['Hello World!']

if __name__ == '__main__':
    from wsgiref.simple_server import make_server
    server = make_server('127.0.0.1', 8080, app)
    server.serve_forever()

Point your browser at http://localhost:8080 and you should see “Hello World!”.

Adding profiling information to this application is as simple as wrapping the application function in some profiling middleware:

app = ProfileMiddleware(app)

Our example now looks like this:

import time

def app(environ, start_response):
    time.sleep(2)
    start_response('200 OK', [('Content-Type', 'text/html')])
    return ['Hello World!']

if __name__ == '__main__':
    from wsgiref.simple_server import make_server
    from wsgiprofile import ProfileMiddleware
    app = ProfileMiddleware(app)
    server = make_server('127.0.0.1', 8080, app)
    server.serve_forever()
