Utilities designed to simplify tuning of linux network stack and keep you from manually evaluate affinity maps / cpu masks.

• BaseTune
  • RxBuffers - increases RX-buffers of NIC (ethtool -G eth1 rx 2048)
  • CPUBasedTune
    • RSSLadder - sets CPU affinity for NIC's queues
    • AutoSoftirqTune
      • AutoRPSTune - sets RPS cpu mask
      • AutoXPSTune - sets XPS cpu mask

1. All utilties aware of PCI belonging to NUMA-node and use CPU's bound to same NUMA node by default.
2. You can override almost everything - socket, CPU list/mask.
3. --dry-run mode, no settings will be changed, but you'll see what happens.
