ZGC(Z Garbage Collector)是 Java 11 引入的一种低延迟垃圾回收器,旨在减少垃圾回收时的停顿时间,并能够在大规模堆内存的环境下提供可预测的低停顿时间。ZGC 是一个并发、并行的垃圾回收器,专为大内存(例如多 TB)的系统设计,并且采用了很多创新的技术以避免长时间的 STW(Stop-the-World)停顿。 1.

The types of Java garbage collectors define the type we use to develop the program. Garbage collection is an important feature of Java. In Java, we use garbage collection to free up memory that is no longer in use. The garbage collector tracks all objects that are still in use and marks ...

Java's memory management is highly appealing to programmers as it relieves them from the burden of manual memory allocation and deallocation. The automatic garbage collector in Java efficiently reclaims memory for reuse, eliminating the need for explicit memory management. When objects are created, ...

Java 11 has recently been feature frozen and contains some really great features, one in particular we’d like to highlight. The release contains a brand new Garbage Collector, ZGC, which is being developed by Oracle that promises very low pause times on multi-terabyte heaps. In this article...
Shenandoah是一个超低暂停时间的垃圾收集器,通过与运行中的Java程序同时进行更多的垃圾收集工作来减少GC的暂停时间。CMS和G1都对实时对象进行并发标记。Shenandoah增加了并发压缩功能。 Epsilon Collector(-XX:+UseEpsilonGC) – JDK 的无为收集器 JDK 11中引入的Epsilon垃圾收集器是一个实验性的收集器,只分配内存。它...

Full GC and Concurrent Garbage Collection in Java The concurrent garbage collector in java uses a single garbage collector thread that runs concurrently with the application threads with the goal of completing the collection of the tenured generation before it becomes full. In normal operation, the ...
