How We Reduced API Latency by 40% (Quick Lessons)?

Optimizing application performance doesn't always require a complete rewrite. Small architectural tweaks often give the biggest speed boosts.

Here are 3 simple techniques we use when optimizing applications:

1. Database Indexing: Ensure your foreign keys and frequently searched columns are properly indexed to eliminate slow table scans.
2. Redis Caching: Cache repeated database reads and expensive API calls in memory for sub-millisecond response times.
3. Payload Reduction: Use selective database queries (only fetching necessary fields) instead of SELECT *.
