The above parameters increase the InitialHeapSize (-Xms) to 4GB (4096 MB) and MaxHeapSize(-Xmx) to 6GB (6144 MB). If the Java heap itself is small (-Xmx), the JVM may allocate it in the lower 4GB of address space along with the Class Pointers and Monitors/Locks. What is minus XMS minus XMX while starting JVM?
