NSK-

In the preceding output, the JVM process ($JSV1) uses 331 MB of swap space and has two segments allocated.

This JVM process was started with a heap size of 256 MB, which shows that apart from the Java heap, the process

requires about 75 MB for process-specific and application-specific data.

Note: To get an applicable sample of the swap usage for a particular JVM process, check this swap

usage at steady state, where all the native components used by the JVM have been fully initialized and

are running.
