Available processing resources where?
On the application server?
The problem statement is bad, because why is it a
problem if the resources are not consumed?
The question is: is the response time and the throughput ok?
If not, that would be a real problem.
Are your top-level problem staters just pissed off
because they cannot get the machine in trouble no matter
how much test load they apply?
If you have a performance problem, the first thing you must find
out is where the performance bottleneck is: network,
CPU, I/O, or memory? And on which machine, if there
are more than one. You can continue once you know that.
