I am looking at adding Flash disk to the system and creating 2 more LPARS.
So the question is would it be of benefit there.

For anyone attending NAViGATE and interested in performance, I have a
session “Understand your IBM i Performance Signature” where I explain how
to use the performance data investigator and what the charts tell you.
Collection Services data can tell you a lot about what resources are
constrained and where you can benefit from hardware upgrades.
It can also show you if you have contention or scaling issues - throwing
hardware at a system with contention issues won’t help.

That answer is: "it depends"

Is the system processor constrained? IE: is the CPU % at or near 90%
during peak times? Is there latent demand that is only met after a period
of waiting?
Is the system memory constrained? Are paging and faulting levels high
enough that the system spends quite a bit of resource moving memory around?
Is the system I/O constrained? Is the system waiting for I/O
operations to complete before moving on to the next task? Look at Disk
busy during peak loads.

Each of those questions can be answered by the performance tools, which
will then guide you where to spend your money. Adding a core will most
likely improve system responsiveness either way since I/O and Memory also
include using system resources to maximize them, but that may not be the
root cause of the performance issue.

Check out Dawn May's blogs regarding using the performance tools to
diagnose the problem. Then you will spend the correct money on the correct
thing. Don't know how to use the tools; get your business partner or an
independent consultant to look at it. IBM will do it as well via the Lab
Services Group.

Subject Question on effectiveness of additional processors

How effective are additional processors on the system.

We have a Power8 with 1 processor activated.
If we activate another processor or 2, what benefits should I see?
I have heard that the additional processor will not make much
difference,
so why would IBM provide for additional processors?

What am I missing?

TIA, Darryl Freinkel.
