How ZGC Achieves Sub‑10 ms Pauses and Scalable Memory Management

This article explains ZGC’s evolution from an experimental feature in JDK 11 to a production‑ready collector in JDK 15, detailing its sub‑10 ms pause guarantee, memory‑mapping architecture, colored pointers, region layout, read barriers, and the multi‑phase concurrent collection process that together deliver low‑latency, high‑throughput garbage collection for Java applications.

Understanding Android ART CC Collector: GC Challenges, Implementation Principles and Performance Optimization

The article thoroughly explains Android ART’s Concurrent Copying (CC) garbage collector—its terminology, correctness and progress requirements, engineering challenges, classic and Android‑specific algorithms, region‑based design with bump‑pointer allocation, performance benefits such as 32% lower heap usage and sub‑millisecond pauses, and its trade‑offs including doubled reserved heap space and migration overhead.

Shenandoah GC’s Concurrent Thread Stack Processing Slashes Pause Times to Sub‑millisecond in JDK 17

This article explains how Shenandoah OpenJDK's new concurrent thread‑stack processing, introduced in JDK 17, dramatically reduces garbage‑collection pause times to sub‑millisecond levels by using stack watermarks, and provides practical configuration guidance and benchmark results.
