Large Python webapp, needed to demonstrate that large Python apps start fast

I want to demonstrate that even a fairly large Python webapp actually doesn't take (relatively) much time to get up and running. It currently takes at least 15 minutes to redeploy our existing application (Java on Tomcat).

What I'm looking for:

• Large (bigger is better, but at least a couple thousand lines)
• Webapp, preferably Flask, though other micro frameworks or Django or even Tornado et. al are fine.
• Database access, preferably quite a bit of it

One option is Trac. According to cloc:

So that's 50,000, weighing in (according to the pypi page) at a whopping 3MB. After install, my virtualenv directory was about 20MB.

• Good example. For some more details, see my answers here, here, and here to get an idea about its capabilities. It's pretty modularized, and not that difficult to enhance it with your own modules (I once contributed a Log-Viewer to it). – Izzy Sep 24 '14 at 22:20

Plone is an ECM server with 700k lines of code, written in Python (on the Zope framework).
It uses a database and has a web interface.

An even bigger one was Nuxeo, but in 2005 it was rewritten from Python to Java.
