Helmut,

   Performance, like beauty, is in the eye of the beholder. Ideal thresholds only 
exist in poor tuning courses and poor tuning books. IMHO, the wisest thing to do would 
be to collect information at a time when performance is perfectly satisfactory and use 
it as a baseline. Then check when there is some _significant_ difference with your 
baseline. If nobody complains, it means that you can probably allow pretty wide 
variations for some values. However, if users do really notice (and it's not purely 
psycho-somatic, as it sometimes is) some degradation, it will be time to enquire.
But bear in mind that the most significant indicators will not necessarily be the same 
ones for all applications, nor even for all times of day.
Also, be careful to collect some information about the actual, business-related work 
being done. I have seen people complaining that they didn't have the same performance 
as 6 months earlier and forgetting that they were processing twice as many invoices or 
whatever. Granted, a well-written application should scale. But at least it helps you 
explain even the most Oracle-challenged manager that it isn't a simple tuning matter 
(it will be harder to explain that it isn't a question of throwing more hardware to 
the problem either, but this is another story).
