Excessive GC Overhead in Java: Understanding and Solving High Garbage Collection Usage Table of Contents What is Excessive GC Overhead? Common Causes of Excessive GC Overhead Implications of High GC Overhead How to Detect Excessive GC Overhead Key Strategies to Resolve Excessive GC Overhead Conclusion Frequently Asked Questions (FAQs) Garbage collection (GC) is a critical aspect of memory management in Java. While Java’s automatic memory management system frees developers from manual memory allocation and deallocation, it can lead to performance bottlenecks when GC processes become too frequent or resource-heavy. One common problem faced by Java developers is “Excessive GC Overhead,” where garbage collection consumes an unreasonable amount of system resources, significantly degrading performance. In this blog post, we will dive deep into the causes of excessive GC overhead, its implications on Java application performance, and strategies to mitigate it. We ...

Table of Contents What is a Memory Leak in Java? Why Do Unclosed Streams and Sockets Cause Memory Leaks? Types of Streams and Sockets in Java How Do Unclosed Streams and Sockets Lead to Memory Leaks? The Importance of Closing Streams and Sockets Properly Best Practices to Avoid Memory Leaks from Unclosed Resources Tools to Detect and Prevent Memory Leaks Conclusion 15 Frequently Asked Questions (FAQs) Understanding Memory Leaks in Java: The Impact of Unclosed Streams and Sockets Memory leaks in Java are a common problem that developers face while working on large-scale applications. One of the most overlooked causes of memory leaks is unclosed resources, particularly streams and sockets. While Java provides automatic garbage collection, it does not handle the proper closing of resources such as file streams, network connections, and database connections. If these resources are not closed properly, it can lead to memory leaks that degrade application perf...
