Database Performance: Indexing and Query Optimization
Most application slowness comes from the database, not the code. The famous N+1 problem, unindexed queries, and selecting columns you don't need all accumulate silently until performance collapses under load.
Practical fixes: use eager loading to avoid N+1, add indexes on columns used in filtering and joins, and monitor slow queries with tools like Laravel Telescope. Always measure before optimizing — never guess.
