Tuning the Linux kernel with AI, according to ByteDance

"Generally speaking, the Linux kernel works just fine for most tasks. But, to get the most from it for a particular job, you must fine-tune it by setting its parameters for the best possible results."

Is this really so, apart from edge cases? Because I've rarely encountered that need in my professional career. There are many blogs about how to tune TCP parameters and similar but most of it is more like snake oil and many people seem to agree the kernel ships with sane defaults.

For example "ByteDance is working on tuning Linux memory management": what options are there to tune?

To be fair to them, some Linux defaults are atrocious IMHO.

For example mq-deadline ALWAYS performs badly in desktop tasks. Launching a Steam download alone is enough to kill a Linux machine using that scheduler. Therefore I feel like we need this.
