Hi, all,

@Krishna Actually, I believe that in sone cases, allocating memory on a
specified Numa node can be of interest, especiallly in terms of
performance. For example, each PCI device is associated with a Numa node.
Projects like DPDK are NUMA aware in the sense that memory is allocated on
a specified NUMA node. This contributes to boost performance.

Regards,
Rami Rosen
