JVM 选项 -Xss - 它究竟做了什么? [英] JVM option -Xss - What does it do exactly?

问题描述

它说这里 -xss是用来设置线程栈大小"的，具体是什么意思呢?谁能帮我理解这个?

It says here that -Xss is used to "set thread stack size", what does it mean exactly? Could anyone help me understand this?

推荐答案

Java 应用程序中的每个线程都有自己的 堆栈.堆栈用于保存返回地址、函数/方法调用参数等.因此，如果一个线程倾向于通过递归算法处理大型结构，它可能需要一个大堆栈来存储所有这些返回地址等.使用 Sun JVM，您可以通过该参数设置该大小.

Each thread in a Java application has its own stack. The stack is used to hold return addresses, function/method call arguments, etc. So if a thread tends to process large structures via recursive algorithms, it may need a large stack for all those return addresses and such. With the Sun JVM, you can set that size via that parameter.
