XMX, XMS and XSS in JVM

Hello,

Xss refers to setting the stack size of each thread. This depends on your program, how much memory a thread needs to occupy, how many threads may be running at the same time, etc.

1. -XMS indicates the memory allocated during JVM startup. For example, Xms200m indicates that 200 MB is allocated.

2. -XMX indicates the maximum memory allocated during JVM running. For example, -Xms500m indicates that the JVM process can occupy a maximum of 500 MB memory.

3. -XSS Memory size allocated to each thread started by the JVM.

Hope this helps
Thanks
