Title: RE: [IBMVM]

Hi Brian: Where are you getting this data from? zvm doesn't "swap" it pages. It will page to expanded storage and/or dasd, and migrate pages from xstore to dasd paging. It will form blocks of pages, but swapping, per se, hasn't existed in vm since, well, hpo.
What product is reporting this data? Is this linux data, which would also be a strange reporting method?

Would someone please shed light on the following for me. What is the
dif from swaping to paging other than swaping is using the swap
space? I can't seem to find much info on paging? I believe if I'm
swapping heavily that's bad, but where does the pageing go and is it
bad for perf? THANX!!!




  % Swap space used          0%
Swap-in rate               0/s
Swap-out rate              0/s
Page-in rate           0.066/s
Page-out rate         50.133/s
