Performance Optimization
A slow endpoint is rarely slow for one obvious reason — it's usually three or four smaller ones stacked together. This module is how to find them systematically instead of guessing.
Learning objectives
- Beginner: Use Actuator metrics to identify which endpoint is actually slow before trying to fix anything.
- Intermediate: Recognize connection-pool exhaustion as a cause of intermittent slowness under load.
- Advanced: Design a load test that reproduces a production performance issue locally before attempting a fix.
