Optimizing Spring Boot Performance
Deep dive into JVM tuning, HikariCP configuration, and lazy loading strategies for high-scale apps.
Java Performance
Performance tuning a Spring Boot app starts with understanding where the time is actually spent. In this article I walk through: - Choosing the right JVM flags for server workloads - Configuring HikariCP for efficient connection pooling - Reducing N+1 queries using Hibernate fetch strategies - Caching expensive calls with Spring Cache I also cover a small case study from my Student Management System project where optimizing a single report endpoint dropped the response time from 2.3s to 280ms.
