What is Django ORM?
To Proceed further, first, let’s discuss the basics of Django ORM. What it is and what role it plays. Django supports object-relational mapping and it is one of its most important features.
Django’s ORM is basically a Python-based technique to build SQL to query and change your database and obtain results.
We have a lot of options to optimize the Queryset thanks to Django ORM. Always keep in mind what you need and don’t require. It is simple to optimize our Queryset if we are aware of our requirements.
Ways to see Database Performance?

Database outages may not be detected until it’s too late and the company is losing money and clients if there isn’t effective monitoring in place.

- Use QuerySet.explain() to understand how specific QuerySets are executed by your database.
- Use silk library to view DB performance.
- Write the below code in Django settings.py file
