I keep saying we should be buying some memory - 1/2 dozen WAS guests at
a time kinda adds up after a while :) But this is a test/dev system,
so the pain is only us and not the real customers!

Most likely your DASD paging rate would go up when you convert some
expanded into main memory in this system.
Oh, and have a look at what you're using expanded storage for right
now. Make sure not to set MDC not to use expanded storage, but use it
for paging only.
