Improve django.setup() and app loading performance

[Rich Jones]

I imagine that this is an area that hasn't really been given much consideration with regards to optimization, because it isn't relevant to normal Django deployments. However, with "serverless" deployments (those without any permanent infrastructure), this becomes quite relevant as we have to call setup() every request.

This ticket is for discussing performance optimizations to Django's setup method. (A sample output for profile is available here: ​https://github.com/Miserlou/django-zappa/issues/24 )

For starters - can we load apps in parallel?

Generally, it's better to raise broad ideas on the DevelopersMailingList and open tickets for specific action items.

It doesn't seem like an issue anymore to me, since you should not be calling setup() every time (which was the end of the discussion, since there was a way to avoid calling it on every request).
