Tuning the cache sizing agent for accurate memory consumption estimates

WebSphere® eXtreme Scale supports sizing the memory consumption of BackingMap instances in distributed data grids. Memory consumption sizing is not supported for local data grid instances. The value that is reported by WebSphere eXtreme Scale for a given map is very close to the value that is reported by heap dump analysis. If map object is complex, the sizings might be less accurate. The CWOBJ4543 message is displayed in the log for any cache entry object that cannot be accurately sized because it is overly complex. You can get a more accurate measurement by avoiding unnecessary map complexity.
