VM is very effective about keeping "low priority" work in the background. If you see that one user seems to be hogging the system, it is probably because there are spare cycles that nobody else wanted to use. The caveat is that on a fully loaded system, even that work does get its fair share of CPU cycles, so it can get in the way of other work.

A question - how effective is the z/vm priority scheme in defining the lower priority work and does that effectively prevent looping/dumping/troublesome low priority work from impacting your high priority production work?
