Spring is a widely used framework on JVM based programming languages to enable rapid application development. Spring is built on top Inversion of Control (IoC) principle which minimizes errors introduced during development and provides customizability, extensibility and flexibility for the applications being developed.
As of writing this, Spring offers a wide range of sub modules/projects from simple Jdbc Templates to advanced Cloud deployments. With the emergence of Spring Boot, the microservices framework of Spring, the usage for Spring skyrocketted and popularity to learn and use Spring Boot is ever so high today.
But the ultimate question remained for years was that, how one can improve the performance of Spring Boot applications so that they have very low latency when it comes to load up. This post looks at some ways that can be used to optimize a Spring Boot application so that it runs faster.
Spring was designed to be lightweight by default and Pivtoal engineering team for Spring cares deeply about performance as of now Spring Boot, HTTP: starts in under 1 second and uses less than 10 Mb of Heap. But following steps can be used to increase performance,
Furthermore, Lazy loading of Beans and subsystems can be used to further improve performance;
Use for example the Lazy Loading Actuator like below to break the application into modules and initialize each one separately on demand.
org.springframework.boot.experimental spring-boot-lazy-actuator 1.0.0.BUILD-SNAPSHOT
Finally use tools to measure the peformance to further improve;
