At most, we'll have to agree to disagree. A "tuning" of the system (at
least from my experience) is about system performance, not whether the
system will crash or not. You may define the word to mean something
else but that's your thing.

The reason I'm aggressively discussing this is that labeling the
problem as "tuning" will, for any non-trivial task which has some
growth in system load, result in a server that needs constant tuning
just to survive another day. What is tuned today may as well result in
a crash tomorrow if the load rises. Web servers are notorious for this
(though other types have of course similar behaviour) - a
"slashdotting" of a "properly tuned" FreeBSD system with ZFS will not
result in a slowdown - it will result in the system crashing. This is
not acceptable, and therefore dismissing it as "just tuning" is
counterproductive and bad engineering.
