Also you must be careful adding storage you may not need because, depending on what OS you are using, the RSM algorithms for determining the 'least recently used' pages can take more CPU if you have more real storage to search.
That's what I already wrote. I also wrote, that increase will be so
small, so for sure it won't be significant, and likely it won't be
measureable.
We're talking about 8GB total.

Since we're not paging on those systems, would we get any benefit from
allocating additional storage to them? Or would we just be spending
DASD space (because the backing store for paging would have to be
bigger to accommodate the additional storage) for no benefit?
What applications are in use ?
In many cases you can increase buffers and get better performance.
Theoretically more storage means more CPU cycles, but I strongly believe
it won't be tangible.
More RAM doesn't necessarily mean more AUX (page datasets).

Or power down the z9, remove the book, remove some DIMM chips and put it in your
child's PC - games need a lot of RAM </joke>
