CP keeps an eye on the performance of the page volumes when it has to select
a device to page out. The fastest device will win. If that happens to be a
"small" 3390 with an occupancy of e.g. >50%, it may be a bad choice as the
block paging will be less effective.
So: if you have enough volumes t
Look at past SHARE presentations on the subject as well the Redbooks.
They carry a wealth of information related to Linux guests and paging.

That's why we converted everything to -9s as quickly as we could. The mixed
size configuration was in reaction to a crisis. All were made -9s before the
next IPL. It took time to (a) obtain the new DASD (it was in-house as MVS
spares, connected to VM , but offline), (b) format it and (c) update
We will, to the extent we can, but not quickly enough to avoid using mod27's as
a stop-gap for now.
