• Django Silk - Silk is a live profiling and inspection tool for the Django framework. Silk intercepts and stores HTTP requests and database queries before presenting them in a user interface for further inspection.
• Django Debug Toolbar - A configurable set of panels that display various debug information about the current request/response.
• pyinstrument - Call stack profiler for Python. Shows you why your code is slow!
• cProfile - cProfile and profile provide deterministic profiling of Python programs.
• dj-tracker - dj-tracker is an app that tracks your queries to help detecting some possible performance optimisations listed in Database access optimization

• django-auto-prefetching - Never worry about n+1 performance problems again (DRF views level).
• djangorestframework-queryfields - Allows clients to control which fields will be sent in the API response.
• django-virtual-models - Improve performance and maintainability with a prefetching layer in your Django project.
• django-perf-rec - Django-perf-rec is like Django's assertNumQueries on steroids. It lets you track the individual queries and cache operations that occur in your code.
• django-auto-prefetch - Automatically prefetch foreign key values as needed (ORM level).
• django-zen-queries - Explicit control over database query execution in Django applications.
• nplusone - Auto-detecting the n+1 queries problem in Python.
• django-pickling - Efficient pickling for Django models.
• django-test-query-counter - A Django toolkit for controlling query count when testing.
• PgBouncer - Lightweight connection pooler for PostgreSQL.
• psycogreen - Integration of psycopg2 with coroutine libraries.

• Database access optimization - Outlines the steps to take when attempting to optimize your database usage.
• Django Performance Improvements - Part 1: Database Optimizations
• Automating Performance Testing in Django
• Performing raw SQL queries

• django-cacheback - Smart caching for Django using Celery to refresh cached items asynchronously.
• django-memoize - A cache for function or method results.
• django_model_cached_property - Useful for caching of property results for more time than lifetime of object during the request.
• django-cacheops - A slick ORM cache with automatic granular event-driven invalidation.
• django-cachalot - Caches your Django ORM queries and automatically invalidates them.
• django-cache-machine - Automatic caching and invalidation for Django models through the ORM.
• django-request-cache - A Django app that provides a new cache on every request object. The cache is only kept within the request/response cycle.
• django-ormcache - A cache manager mixin that provides some caching of objects for the ORM.
• Varnish Cache - A web application accelerator also known as a caching HTTP reverse proxy.
• PolyScale.ai - A high performance Data Delivery Network (DDN) that accelerates databases. Using smart caching, it improves query performance, lowers latency and makes data access and scale engineering a breeze, both on premise and at the edge.

• Django's cache framework
• Varnish - 12 Days of Performance

• drf_orjson_renderer - A JSON renderer and parser for Django Rest Framework using the orjson library. Backed by Rust, orjson is safe, correct and fast.
• Django Compression Middleware - Django middleware to compress responses using algorithms such as Zstandard, Brotli, and gzip.
• serpy - A super simple object serialization framework built for speed.
• django-rest-marshmallow - Marshmallow schemas for Django REST framework.
• marshmallow - An ORM/ODM/framework-agnostic library for converting complex datatypes, such as objects, to and from native Python datatypes.

• Improve Serialization Performance in Django Rest Framework - How we reduced serialization time by 99%!
• Python Serialization Benchmark - A set of benchmarks for Python serialization frameworks.

• Celery - Distributed Task Queue.
• Celery Flower - Real-time monitor and web admin for Celery distributed task queue.
• django_dramatiq - A Django app that integrates with Dramatiq.
• Django-RQ - A simple app that provides django integration for RQ (Redis Queue).
• Django Q - A multiprocessing distributed task queue for Django.

• Improving Scalability, Reliability, and Efficiency of a Python Service with Gevent

• gevents - A coroutine-based Python networking library that uses greenlet to provide a high-level synchronous API on top of the libev or libuv event loop.

• Is Django too slow?
• Gunicorn Async Workers with gevent

• Locust - An easy to use, scriptable and scalable performance testing tool.
• hey - HTTP load generator, ApacheBench (ab) replacement.

• Sentry SDK - The official Python SDK for Sentry.io (has an APM offering).
• statsd - Daemon for easy but powerful stats aggregation.
• django-prometheus - Export Django monitoring metrics for Prometheus.io.
• django-postgres-metrics - A Django application that exposes a bunch of PostgreSQL database metrics.
• Grafana - Operational dashboards for your data here, there, or anywhere.
