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.
The application architecture and performance are often assessed through reports like Word documents and PowerPoint presentations, which can misrepresent facts. For accurate insights, it's essential to analyze runtime artifacts such as Garbage Collection Logs and Heap dumps, despite their complexity. Tools like GCeasy.io can simplify this analysis for clearer understanding.
