Something I would love to find is a practical/succinct guide on Linux kernel performance tuning. I'd love it to give examples of sysctl's you'd adjust for specific use cases like:

- a real-time kernel

- a single user mode kernel

- an embedded device kernel (like an esp 32 or rpi)

- general purpose desktop use (surely there are gems in here)

- to use the linux kernel as a hypervisor hosting others

- tuning the linux kernel for within a vm (guest to another hypervisor)

- tuning for gaming performance

I myself do not know enough about sysctls, and I'm sure it's a goldmine.
