		<title>SMP Affinity</title>

		<para>
			This system is automatically using SMP affinity for every physical
			network controller, if supported.
		</para>

		<para>
			A processor core is assigned to handle all interrupts of a certain
			network controller which will result in minimising cache misses,
			reducing network latency and quite possibly increasing throughput.
		</para>

		<para>
			The algorithm is trying to balance all network controllers across
			all processors.
		</para>

		<para>
			See /proc/interrups for the distribution of interrupts. 
		</para>
