I’m building a web application using Python and PostgreSQL, and because it will be fairly high traffic, I need to optimise my database queries for performance.

I’m still in the developmental stage but some queries are taking a long time to execute, and I’m wondering what techniques I can use to improve efficiency.

Should I use indexing, caching, or query optimisation tools like EXPLAIN and ANALYZE? How can I identify bottlenecks in my queries and tables?

Any advice would be greatly appreciated!

I have also found no duplicates.

Thanks!
