Java 21 introduces virtual threads through Project Loom, enhancing memory efficiency and garbage collection. Unlike traditional threads, virtual threads utilize minimal memory and create fewer garbage collection pauses, improving performance under high load. Tests reveal significantly reduced heap pressure and enhanced system responsiveness, particularly in I/O-heavy applications.
Read moreThe 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.
Read moreJava 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.
