How much memory does Django consume compared to Rails?

[Jason Hsu]

I have deployed two Ruby on Rails sites on WebFaction, and Passenger Rack takes up around 60 MB of memory apiece.

I was planning on replacing my Drupal web sites with Rails, but I'm now considering replacing these Drupal sites with Django.  Given that the baseline memory consumption for a Rails site is around 60 MB, how would a Django site compare?
