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. | |
