In some slightly larger applications, the memory settings of the Java Virtual Machine (JVM) are particularly important, and the GC (garbage collection) setting is the first step in trying to achieve good efficiency in the project. PermGen space: The full name is permanent Generation space. is a permanently saved area for storing class and meta information, and class is placed in the area of heap space when

XX: When MaxPermSize is set too small, java. lang. OutOfMemoryError: PermGen space is the memory benefit. PermSize and MaxPermSize indicate that the virtual machine allocates memory restrictions for the Permanate generation objects such as class objects and method objects, these memories are not included in Heap (Heap memory.
