This doesn't necessarily find the best parameters, and it doesn't necessarily do it easily. From my reading, it will converge on a local optimum, and it may take some time to do that. In theory, I don't see why the kernel couldn't have a parameter-auto-tune similar to this. In practice, I think the kernel has to work in so many different domains, it'd be impossible to land on a "globally good enough" set of tuning heuristics. I'm far from a kernel developer, so I'm ready to be corrected here. IMO if we ever see something like this deployed widely, it will be because a popular distribution decided to install it by default.
