by the runtime system of a programming language that uses automatic memory management, such as Java or Python. During the process, the garbage collector pauses the program's execution to perform the search for garbage objects, which can result in a temporary slowdown in the program's ...
Java 的 ZGC(Z Garbage Collector) 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...
