Hands-On High Performance with Spring 5

By: Chintan Mehta, Subhash Shah, Pritesh Shah, Prashant Goswami, Dinesh Radadiya

Overview of this book

While writing an application, performance is paramount. Performance tuning for real-world applications often involves activities geared toward detecting bottlenecks. The recent release of Spring 5.0 brings major advancements in the rich API provided by the Spring framework, which means developers need to master its tools and techniques to achieve high performance applications. Hands-On High Performance with Spring 5 begins with the Spring framework's core features, exploring the integration of different Spring projects. It proceeds to evaluate various Spring specifications to identify those adversely affecting performance. You will learn about bean wiring configurations, aspect-oriented programming, database interaction, and Hibernate to focus on the metrics that help identify performance bottlenecks. You will also look at application monitoring, performance optimization, JVM internals, and garbage collection optimization. Lastly, the book will show you how to leverage the microservice architecture to build a high performance and resilient application. By the end of the book, you will have gained an insight into various techniques and solutions to build and troubleshoot high performance Spring-based applications.

Heap memory

Heap memory is divided into primarily two generations: Young Generation and Old Generation. There is a PERM GENERATION that is a part of heap memory until Java 7, while from Java 8, the PERM GENERATION is replaced by METASPACE. METASPACE is not part of the heap memory but is part of the Native Memory. Set size of METASPACE using the -XX:MaxMetaspaceSize option. It is critical to consider this setting when going to production since if METASPACE takes up excessive memory, it affects the application's performance:

Java 8 memory management

The Young Generation is where objects are created and allocated; it's for young objects. The Young Generation is further divided into Survivor Space. The following is the Hotspot Heap Structure:

The eden area is, by default, bigger than Survivor Space. All the objects are created first in the eden area. When eden is full...
