I honestly don't understand what is wrong with having a general discussion about system performance.
General discussions are not easy via an email mailing list. Stack
Overflow does not even *allow them*:
'You should only ask practical, answerable questions based on actual
problems that you face. Chatty, open-ended questions diminish the
usefulness of our site and push other questions off the front page.
'Your questions should be reasonably scoped. If you can imagine an
entire book that answers your question, you’re asking too much.
'If your motivation for asking the question is “I would like to
participate in a discussion about ______”, then you should not be asking
here. However, if your motivation is “I would like others to explain
______ to me”, then you are probably OK. (Discussions are of course
welcome in our real time web chat.)'

WHy should I not want to see if I can help the system?
You should want to be useful.
It is my opinion that this is the stage of your education where you MUST
start with the reference material. You have had enough exposure to the
vocabulary to get you going. Search the archives of this list and see
what other people have asked and how answers have come in. Go to the
Infocenter. Use the vocabulary you have acquired and search the
relevant portions so you can see /how/ to gather data in order to begin
to make decisions on performance.
For the archives, performance tuning is HARD. Every machine is
different because of the individual workload it has to carry, because of
the individual database and the individual data set within that
database. If you want to have a discussion on performance, you'll need
to post specifics about the machine: model, memory pools, activity
levels, disk arms and utilisation for starters.
A general performance discussion goes like this:
Q: My machine's performance is not good.
A: Buy a bigger machine.
Q: I can't afford a bigger machine!
A: Reduce the workload.
Q: I can't reduce the workload!
A: Then performance is acceptable to the business, by definition.
