Generational Z Garbage Collector would lower garbage collection CPU overhead, lower heap memory overhead, and reduce the risk of allocations stalls, OpenJDK proposal says.

Garbage Collection Tuning Optimising garbage collection in Java is crucial for fintech applications where performance and low latency are key.

Let's look at unpredictability, which occurs when Java must stop and perform a garbage-collection sweep when an object is allocated but there is no free space.
