5.13.2 Memory size used by the object for communicating with redirector

The memory size of Explicit heap used by the object for communicating with redirector is estimated by the following formula:

Memory-size-used-by-the-object-for-communicating-with-redirector
=memory-size-used-in-one-connection#×number-of-connections-with-the-redirector
#

The memory size used in one connection differs depending on the use of the automatic allocation functionality of the Explicit Memory Management functionality. The following is the memory size used in one connection depending on the use of the automatic allocation functionality of the Explicit Memory Management functionality.
