Understanding Postgres Query Optimizer - Part 2 (Ref 21)

Performance optimization is not just a checkbox; it is a core feature of engineering. Designing table layouts, index strategies, and API buffers correctly will increase throughput by 10x. We review common performance traps and how to escape them using standard diagnostic commands.

Scaling modern web portals requires a shift in mindset. Instead of scaling vertically, horizontal scaling allows distributed node instances to handle sudden traffic peaks. We explore setting up load balancing proxies, state replication, and global content delivery networks.
