Database and Backend Performance
Frontend performance can be limited by backend operations. A page that renders quickly still feels slow if database queries take seconds.
Use appropriate indexes, avoid fetching unnecessary columns, paginate large collections, and eliminate N+1 query patterns.
Measure database latency independently from rendering latency so you can identify the actual bottleneck.
Key Takeaways
- Frontend optimization cannot compensate for inefficient database queries.
- Indexes should reflect real query patterns.
- Avoid N+1 queries in server-rendered pages.
