Local memory is hardly needed any more ...

Hi,

In the Heap memory parameter page ( http://goo.gl/mnUKgf ), I can find the following statement:
Local memory is hardly needed any more with modern 64 bit platforms, as the memory requirement can be satisfied by the SAP Extended Memory.
What does this mean ? Can I set the abap/heap_area_dia to 0 ? Or even abap/heap_area_total = 0 ? What are the consequeces ?

In the abap/heap_area_nondia help page you can find:
The value should be high enough for the largest possible background processing context in your SAP system. If the value is too small, SAP Extended Memory is assigned to the background process. This extended memory is not available for dialog work processes.
I'm a bit confused. Why would it be a bad think it bg process take some extended memory. Heap and extended should be only reserver in the physical RAM. So why should I continue to manage 2 different pool of memory?

Regards,
Redge
