Spring Boot Performance Optimization
A practical checklist to improve Spring Boot throughput and latency.
When optimizing Spring Boot applications, measure before tuning and prioritize high-impact changes.
Profile before changing
Capture thread dumps, GC behavior, and hot endpoints using realistic workloads.
Tune connection pools
Use right-sized JDBC and HTTP pools. Over-allocation hurts memory and creates contention.
Cache where it matters
Cache expensive read paths with clear TTLs and invalidation strategy.
Optimize serialization and payloads
Minimize object graphs and trim response payloads for latency-sensitive endpoints.
