autotune-device [--capture] [--forward] [--inet / --management]

capture

• maximum rx buffers size, tx defaults
• queue count = max(min(local NUMA cpus, power of 2), maximum queues)
  • multi-queue - rss-ladder for local NUMA and no autorps/xps
  • single-queue - autorps for all cores local NUMA node and no RSS
• disabled flow control ethtool -A eth1 rx off tx off

forward

• maximum rx/tx buffers size
• queue count default
• autorps on all available cores disregard device's NUMA node and NUMA/socket at all, no XPS
• rss-ladder - not used, all queues on CPU0 by default
• disabled flow control ethtool -A eth1 rx off tx off

inet / management

• buffers default
• queue count default
  • single/multi-queue - autorps/autoxps on local NUMA

TODO

• capture
• forward
• inet / management
• refactor autotune-reductor
