Embodiments are directed to improving remote traffic performance on cluster-aware processors. An embodiment of a system includes at least one processor package comprising a plurality of processor ports and a plurality of system agents; and a memory device to store platform initialization firmware to cause the processing system to: determine first locations of the plurality of processor ports in the at least one processor package; determine second locations of the plurality of system agents in the at least one processor package; associate each of the processor ports with a set of the plurality of system agents based on the determined first and second locations; and program the plurality of system agents with the associated processor port for the respective system agent.
