If you see any paging activity, increase system memory or decrease the size of the JVMs. Be aware that decreasing heap sizes may increase the overhead of garbage collection. Each time a full garbage collection is performed, all of the memory needs to be scanned for garbage. Garbage collections occur more frequently with smaller heaps, which could waste CPU time.

You can check the size of your JVM heaps or cause garbage collection with the ATG VMSystem component at:
