though i dont know much about it, i run linux and most of the documents i hear about tuning edge cases are now either avoided or boilerplated with a strong word of caution. For example: 10Gb ethernet used to require a litany of sysctl.conf chicanery to even approach half the line speed. not the case anymore, and most of the old kernel 2.4 optimisations are either nonsensical in 2023 or actively worsen the performance of the interface.
