I have a Django app deployed using Passenger (I did not choose mod_wsgi because mod_passenger is already there and being used). When I uploaded an MP3 file (900 kB), Google Chrome displays upload % which reached 100% pretty fast but then it took forever for the resulting page. The database (containing the file's metadata) does not show anything uploaded.
The Django logic should be OK because everything works in the development machine (built-in Python server)
My config: Django 1.8, Apache 2.4, Ubuntu 14.04
