G1 GC has been Java’s default garbage collector since Java 9. It’s been designed to provide high performance and low pause times for applications with large heaps, with the aim of balancing latency and throughput. To achieve this balance, G1 performs its work concurrently with the application, making the application threads share the CPU with GC threads. This situation requires thread synchronization, which unfortunately lowers throughput and increases latency.
