ZGC vs Shenandoah: Ultra-Low Latency GC for Java

In the world of high-performance computing—where microseconds matter—Java has often been scrutinized for its garbage collection (GC) pauses. Traditional GCs like G1 and Parallel GC introduce unpredictable stop-the-world (STW) pauses, making them unsuitable for high-frequency trading (HFT), real-time analytics, and low-latency microservices. However, with the introduction of Z Garbage Collector (ZGC) and Shenandoah GC, Java now competes with low-latency …
