33 | <para> | |
34 | This page contains a summary of some performance tuning techniques | |
35 | that this system is using. | |

40 | <title>SMP Affinity</title> | |
41 | ||
42 | <para> | |
43 | This system is automatically using SMP affinity for every physical | |
44 | network controller, if supported. | |
45 | </para> | |
46 | ||
47 | <para> | |
48 | A processor core is assigned to handle all interrupts of a certain | |
49 | network controller which will result in minimising cache misses, | |
50 | reducing network latency and quite possibly increasing throughput. | |
51 | </para> | |
52 | ||
53 | <para> | |
54 | The algorithm is trying to balance all network controllers across | |
55 | all processors. | |
56 | </para> | |
57 | ||
58 | <para> | |
59 | See /proc/interrups for the distribution of interrupts. | |
