When Scheduling mode is shared mode
In the case of the Shared mode, the memory access of logical processors are generally
dispersed to multiple nodes, and access to local memory and remote memory are
intermingled.
The memory access performance of all LPARs in shared mode will be between the local
one and remote one, and there will be almost no difference between LPARs. (See
LPAR 1 and LPAR 2 below.)
