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.

JAX London is an annual October conference for Java and Software Architecture professionals. In 2024, architect Ram Lakshmanan presented on "GC Tuning," showcasing Fortune 500 case studies. Attendees rated the session highly at 4.25 for talk quality and speaker knowledge, providing insights on optimizing Garbage Collection performance.
Enterprise Java applications often use up memory quickly, leading to extra computing costs. If memory is under-allocated, it causes performance issues, shown by frequent Full GCs and low GC efficiency. Analyzing GC logs can identify whether memory is under or over-allocated, offering useful insights for optimal memory allocation.
