 Rich,

The opening thesis of the tree falling in the forest and not making any noise 
is sound (pardon the pun) -- it is the basis for the triaged reactive tuning 
that many of us perform. There is always a threshold under which we ignore 
problems, and that threshold could be a system-wide value or it is complaints 
from users.

Hasn't this guy heard of Moore's Law? It's only been around for 40+ years, 
which may explain why he forgot it. I remember similar articles written in the 
late-1980s with the onset of multi-CPU systems, and later (to a lesser extent) 
with multi-core CPUs. Such advances have not reduced the need for tuning, but 
merely reduced the hardware footprint and/or increased user expectations. When 
has *anyone* ever overbought hardware capacity, as opposed to just saving money 
and buying less, or sharing that higher capacity amongst more workloads? I 
mean, seriously, c'mon... :-)

Efficiency and tuning never goes out of "style", and an inefficient application 
can crush any system, no matter how huge.

Just because someone got away with KIWI (kill it with iron) yet again does not 
make a seismic shift make.

Thanks Rich!

-Tim

I think I'm gonna be 
sick:http://www.sqlmag.com/article/Performancetuning/ssds-performance-tuning-experts-milkman-139591This
 mentality **in a database professional** completely escapes me. Itbrings to 
mind that I just "upgraded" my Blackberry to one that has 2x theCPU and 5x the 
RAM -- and still works just as bad as the one it replaced (ifnot worse).Anyone 
from the Oracle camp advocating/predicting hardware-based "tuning"?Rant 
over.Rich--//www.freelists.org/webpage/oracle-l
