Java now competes with low-latency languages like C++ and Rust with the introduction of Z Garbage Collector (ZGC) and Shenandoah GC.ZGC and Shenandoah offer sub-millisecond pause times, making them ideal for latency-sensitive applications.ZGC performs almost all GC work concurrently and has ultra-low pause times, regardless of heap size.Shenandoah GC provides balanced latency and throughput with sub-10ms pauses and concurrent evacuation.
