我的java线程需要多少内存？ [英] How much memory does my java thread take?

问题描述

有没有办法找出我的java线程在VM中占用多少内存？

Is there a way to find out how much memory my java thread is taking in the VM?

例如，使用堆栈跟踪转储或其他方法。

For example, using stack trace dump, or some other means.

谢谢

推荐答案

Java线程将堆用作共享内存。各个线程有自己的堆栈（可以通过 -Xss 命令行选项设置其大小，默认为512KB），但所有其他内存（堆）不属于特定的线程，并询问一个特定的线程使用多少是没有意义的。

Java threads use the heap as shared memory. Individual threads have their stack (the size of which you can set via the -Xss command line option, default is 512KB), but all other memory (the heap) does not belong to specific threads, and asking how much of it one specific thread uses simply does not make sense.
