Database performance has a direct impact on application performance. Laravel makes database access convenient, but inefficient queries can still become a bottleneck.
Use eager loading to avoid N+1 queries, select only the columns you need, add indexes to frequently filtered columns, and inspect generated SQL when performance becomes an issue.
Optimization Checklist
- Check for N+1 queries.
- Add appropriate database indexes.
- Avoid loading unnecessary columns.
- Use pagination for large datasets.
- Review complex joins and subqueries.
Small query improvements can make a significant difference on production systems.
