By %USE I meant page slots used, meaning increase in page out.

> Why does workflow drop from %use?

too much juice wasted on paging out/in.

The issue is not page config, but increase in paging out/in & drop in workflow.

So when we look at demand paging for the month, we roughly see:

......|...........|..............|...........
......|...........|..............|...........
......|...........|..............|............
----|--------|----------|--------

the spikes are when a few big sort jobs end up running at the same time.

data involved is bigger than 60K tracks.
