   8 DESCRIPTION
   9 -----------
  10 This page contains a summary of some performance tuning techniques
  11 that this system is using.
  12
  13 === SMP Affinity
  14
  15 This system is automatically using SMP affinity for every physical
  16 network controller, if supported.
  17
  18 A processor core is assigned to handle all interrupts of a certain
  19 network controller which will result in minimising cache misses,
  20 reducing network latency and quite possibly increasing throughput.
  21
  22 The algorithm is trying to balance all network controllers across
  23 all processors.
  24
  25 See /proc/interrups for the distribution of interrupts.
