Lately, mith mulptiple-socket SMP architectures, it started to be essential to know your system and set the PCIe devices and application in more favorable physical locations, in order to not be hit by system bottlenecks or generate more overhead in general, which could hurt performance application. 

This page is to aggregate different documentation resources that will help on this task.

Basically we need to make sure that all involved devices (NICs, storage controllers) are handled in the same NUMA node, in order to avoid foreign memory access that hurts performance in different ways.
