WBI performance tuning and memory management

Java Virtual Machines (JVMs) externalize multiple tuning knobs which may be used to improve WebSphere Business Integration application performance. These knobs control issues related to garbage collection, heap size, threading, and locking. Because the ICS server and its components (maps, collaborations) as well as most of the adapters are written in Java, the performance of the JVM has a significant impact on the performance delivered by an ICS application.

For a detailed description of performance considerations for WebSphere business integration, navigate to the IBM software support site and search on "WBI performance tuning," or consult the following document, which is updated regularly:
