Introduction: Why Optimize Spring Boot Performance?
Spring Boot makes it easy to build applications, but without proper optimizations, your app might experience:
✅ Slow startup times
✅ High memory consumption
✅ Slow database queries
✅ Poor response times under high load
In this guide, we’ll explore 10 proven performance tuning tips to make your Spring Boot applications faster and more efficient.
1️⃣ Optimize Application Startup Time
Spring Boot applications can take time to start due to eager bean initialization.
✅ Enable Lazy Initialization
Lazy initialization delays the creation of beans until they are needed, improving startup time.
📌 Add to application.properties:
spring.main.lazy-initialization=true2️⃣ Reduce Unnecessary Auto-Configurations
Spring Boot loads all auto-configurations by default. Disabling unnecessary ones speeds up startup and improves memory usage.
✅ Exclude Unused Auto-Configurations
📌 Disable unused configurations in application.properties:
spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration3️⃣ Optimize JVM Memory Settings
Tuning JVM settings can prevent memory leaks and improve performance.
