IMHO it should be the task of the system to autotune itself. I mean, how
many people know about these knobs, when they don't experience any
serious problems (but might unknowingly be having suboptimal
performance)? I didn't, and I have been using NetBSD for years.
Who _wants_ to fiddle around with obscure sysctl settings, trying to get
to a kernel parameter configuration that might work substantially
better? The system should tune itself, we're not in the 70ies anymore.
