Django too slow on first request

Description (last modified by Sridhar)

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.

Thanks for this ticket, however, Django 2.2 is not supported and we've made a ton of improvements and optimizations since then. To submit a valid ticket you have to propose a concrete optimization targeted to the current main branch.

As a side note, you should ask for help on [support channels ​https://forum.djangoproject.com/]. As for me, deploying a full Django project on lambdas doesn't sound like the best idea.
