61 | The Node parameter will allow you to pick which NUMA node you want to have | ||
62 | the adapter allocate memory from. All driver structures, in-memory queues, | ||
63 | and receive buffers will be allocated on the node specified. This parameter | ||
64 | is only useful when interrupt affinity is specified, otherwise some portion | ||
65 | of the time the interrupt could run on a different core than the memory is | ||
66 | allocated on, causing slower memory access and impacting throughput, CPU, or | ||
67 | both. | ||
