c20f2927 MT |
7 | This page contains a summary of some performance tuning techniques |
8 | that this system is using. | |
9 | ||
10 | === SMP Affinity | |
11 | ||
12 | This system is automatically using SMP affinity for every physical | |
13 | network controller, if supported. | |
14 | ||
15 | A processor core is assigned to handle all interrupts of a certain | |
16 | network controller which will result in minimising cache misses, | |
17 | reducing network latency and quite possibly increasing throughput. | |
18 | ||
19 | The algorithm is trying to balance all network controllers across | |
20 | all processors. | |
21 | ||
39cfece8 | 22 | See /proc/interrupts for the distribution of interrupts. |
