JVM tuning Java heap size parameters influence the behavior of garbage collection. The default shrink period is 15 minutes and the minimum is 1 minute. Connection Pools provide numerous performance and application design advantages:. Like the asynchronous client message pipelining behavior, synchronous clients with Prefetch Mode enabled receive batches of messages when the client invokes the receive method. Note that the steady-pool-size and max-pool-size parameters only govern the number of instances that are pooled over a long period of time.
