JVM性能调优分代的相关内容

jvm性能调优 - 19G1分代回收原理深度图解

Pre上篇文章我们给大家分析了一下G1垃圾回收器设计的思想，主要是把内存拆分为很多个小的Region，然后新生代和老年代各自对应一些Region，回收的时候尽可能挑选停顿时间最短以及回收对象最多的Region，尽量保证达到我们指定的垃圾回收系统停顿时间。这篇文章我们继续一步一图，把G1垃圾回收器工作...

jvm性能调优 - 04JVM分代模型

背景引入介绍一下JVM内存的一个分代模型：年轻代、老年代、永久代。们在代码里创建的对象，都会进入到Java堆内存中，比如下面的代码：这段代码，我们稍微做了点改动，在main()方法里，会周期新的执行loadReplicasFromDisk()方法，加载副本数据。首先一旦执行main()...
