In the server blade of a NUMA configuration, the configuration example of the processor
and the memory to the LPAR, which is recommended from the memory access
performance perspective, is shown below.
When the Scheduling mode is the dedicated mode
There are two types for improving the memory access performance:
• When specifying the physical processor number, and
• When configuring the processor group
When configuring a processor group, it is possible to skip specifying the physical
processor number in the LPAR configuration.
Those are the same memory access performance.
When specifying the physical processor number

The memory access is
always performed to a
local memory and you can
get the best memory
access.
