Shenandoah GC enhances Java application's performance by concurrently managing garbage collection with application threads, aiming for low pause times. This is accomplished through region-based memory management and various tuning parameters. Ideal for low-latency, large heap, and highly concurrent applications, Shenandoah offers modes and heuristics for optimizing performance. Analyzing GC logs aids fine-tuning.
This content debunks three myths about Garbage Collection. Firstly, Minor GCs do pause applications, contradicting beliefs of being harmless. Secondly, Serial GC can perform comparably to G1 GC, challenging the notion that it’s only suitable for development. Lastly, while Garbage Collection is automatic, it incurs significant costs and requires attention to avoid issues.
