gceasy.io is introducing a RESTful API to analyze Java GC logs. Here are a couple of use cases where this Java GC API can be used.
Through our Java performance training program, hundreds of engineers were able to fast track their career growth. Engineers have become Leads. Leads have become managers.
The post explores Java's Garbage Collector (GC), highlighting its automatic memory management benefits and potential performance issues like response time degradation and increased computing costs. It outlines GC types, tuning strategies, and algorithms to optimize performance. Proper understanding and tuning can significantly improve application efficiency and reduce operational costs.
Java 25 introduces Compact Object Headers through JEP 519, reducing object header size from 12 bytes to 8 bytes. This change enhances memory efficiency, leading to lower cloud costs by decreasing heap space usage and garbage collection frequency. As a result, applications experience better performance with reduced memory pressure.

Old enterprise systems prioritized throughput for performance metrics, but modern applications often require low latency due to real-time demands. As heap sizes grow, traditional garbage collectors struggle with predictability in pause times. ZGC and Shenandoah are designed for low-latency environments, offering distinct architectures tailored to different workload requirements. Selecting the appropriate collector depends on specific application needs.
The guide emphasizes the importance of analyzing Garbage Collection (GC) logs in Java for diagnosing performance issues. It outlines how GC logs provide continuous insights into memory behavior, helping identify problems like memory leaks, pause bottlenecks, and inefficient heap sizes. Proper log analysis aids in JVM tuning, promoting system stability and performance.
