Overview
Java性能优化越来越难。曾经，通过引入即时编译器，就能实现8倍的性能飞跃。而今，你可能会有疑问：Java性能还有多大的优化空间？本书直面这一问题，证明对于工程师而言，仍有很多工作可做！作为曾在Java性能工程小组深耕多年的老牌工程师，本书作者透彻解释了JVM和Java平台特性对应用程序性能的影响。
应用程序开发人员和性能优化工程师将了解针对Java 8和Java 11的性能优化措施、工具和方法，也会了解提前编译和一些实验性的垃圾回收器。Java的调优标志数以百计。读完本书，你不必再盲目测试这些标志的效果，而是能够从根本上理解应用程序性能欠佳的原因，并熟练地运用恰当的标志提升性能。
