Good response, Jim. Perhaps one clarification is that you can assign job priority and time slice to sub-systems, which affect CPU allocations to servers like Tomcat.

Subject: Re: Questions about subsystems and performance (both in general and specific to Tomcat)
Processor is not allocated at the subsystem level, rather at the
partition level. While there are methods to control how much memory is
used by a subsystem and its jobs, there is no way I am aware of (at this
point) to control processor at the subsystem level.
Any subsystem will do, but you have to tune it properly. I like to set
up routing to push specific workloads into shared memory pools where I
can not control some of the performance.
None of this is hard once you understand the job routing on the system.

How does one tell which subsystem has more allocated processing power
And when running Tomcat, is there a particular subsystem that it should
be running in, for best performance?
