Hello! Who hasn't run into performance issues with Django projects, right? Especially as the number of active users increases, response times also go up. What methods are you using? How do you manage cache systems? What do you pay attention to in database optimization? Should project-specific situations be considered, or is a general approach preferred? Let's exchange ideas together!
What are the methods to improve performance in Django?

Starting with caching is the most logical approach, and I always use CachéFramework (Redis + Django's cache API). I break views into parts and cache frequently used sections, especially the homepage. But be careful—if there are user-specific data, you need to switch to user-based caching, otherwise everyone sees the same page.
Optimizing database indexes is also crucial. I heavily rely on the `select_related` and `prefetch_related` combo in queries. For example, if you're fetching 10 records from 1000 users, instead of querying them separately, you fetch them all at once. For slow, long-running queries, I analyze them with `EXPLAIN ANALYZE` and add necessary indexes. For small projects, default PostgreSQL settings usually suffice, but as they grow, connection pooling (PgBouncer) and removing unnecessary columns can significantly boost performance.
