Java applications utilize two types of memory: Java Heap and Native Memory. The Java Heap stores application objects and is managed by the Garbage Collector, while Native Memory contains essential runtime structures. Understanding these differences aids in diagnosing performance issues and resolving memory-related errors effectively, enhancing application performance and stability.
Java Heap fragmentation is an interesting problem, which triggers long pausing full garbage collection cycles. In this article we would like to attempt to explain the heap fragmentation.
