Hi,

Yep. But I did say that, as far as I know, the application code is
well implemented. We do use bind variables, whenever we can we parse
once and execute many times, etc.

I have used statspack, and tkprof, and everything, and the conclusion
is that the bottleneck is, simply put, that oracle _has_ to do a lot
of work to do what I am asking it to do.
From you answers I gather that I did not correctly formulate the
question.
Let me try again: supposing there are no big mistakes in the
application, and supposing that we believe that there is a IO
bottleneck, what is the most efficient hardware answer to this?
I can imagine some of them:
But I do not honestly know their effectivity. What is the usual way of
improving IO?
Any advice from the wiser ones would be appreciated. I promise to keep
working in the application side of the question.

A final note: we are talking about reducing response time, not getting more throughput.
