Did you actually see much improvement in any relevant workload
from tweaking these parameters?  If yes what did you change?
And how much did it gain?

Ideally the kernel should perform well without much tweaking
out of the box, simply because most users won't tweak. Adding a 
lot of such parameters would imply giving up on good defaults which 
is not a good thing.
