JVM分析优化的相关内容

jvm性能调优实战 - 31从测试到上线_如何分析JVM运行状况及合理优化

Pre前面两篇文章，已经给大家介绍了jstat、jmap、jhat等工具，可以非常轻松的分析出系统运行时的JVM状况，包括内存使用压力还有GC压力，包括内存中的对象分布情况。这篇文章，我们结合之前介绍过的两个工具，给大家做一个实际开发、测试到上线的一个整体JVM优化的梳理。开发好系统之后的预估性优化...

JVM学习笔记：逃逸分析的优化手段（猜想随笔）

有这样一个问题：对象是在堆中被分配的吗？我想说至少目前是这样的。现在版本的JVM本身就已经默认开启了逃逸分析来优化我们的代码，这种优化的思想有一种错觉是对象在栈上分配了，但其实并不是。实际上对象还是在堆中被分配的，优化的内容只是针对那些未发生逃逸的对象，将对象通过标量替换的手段进行优化了，也就是说将...
