Ordinary ZGC: collect all objects every time Generational ZGC: Recycling by generation We believe that Generational ZGC will be better suited for most use cases than its predecessor. Some workloads may even see throughput improvements with generational ZGC due to lower resource usage....

However, Azul Prime ReadyNow, Spring-boot, etc. support generating checkpoint images according to other rules such as cycles without stopping running Java applications. This function Can also be used in production environments. 4.4.Restore 4....
