Not all workloads are created equal. Different applications use memory in different ways and thus can benefit from different garbage collection strategies. The IBM® Java™ Virtual Machine (JVM) has always supported several different GC policies to support various types of applications. At the same time, hardware is evolving and software must adapt to make better use of it. In IBM WebSphere® Application Server V8 the default garbage collection policy uses both generational and concurrent collection strategies. This article provides a brief description of the garbage collection policies available in the IBM JVM, along with a guide for configuring the new default policy.
