You may find this series of articles interesting: https://lwn.net/Articles/741494/ https://lwn.net/Articles/744507/ https://lwn.net/Articles/746780/ https://lwn.net/Articles/748198/ While they're a little old and they're targetting a much smaller system than yours, they may give you some ideas of things you can try and tools you can use.
