New description:
We have deployed our Django app on lambda, the first request always takes
5-6 seconds excluding lambda cold start times.
My Observations:
- `get_app_list` and `reverse functions` take too long.
- The reverse function to prepare and match uri takes O(n).
- Django adds two URLs for every model we register, so this wait time
increases as we add models or write the Rest APIs.
I am attaching the Cprofile results below. Let me know if there are any
ways to optimize this.
