Reports "MEM" and "WORKINGSET" of the report group MEMORY

The value “Available pages (NPP)” specifies how much real main memory is still available for paging.

Paging operations start to occur if the value “Number of page frames for system global set” (SWS) reaches approx. 80 - 90% of NPP.

If the SWS value increases to above 90% of NPP, an expansion of the main memory should be taken into account. In VM2000 operation it is often (at least as a transitional measure) sufficient to distribute main memory more efficiently between the guest systems. With these high SWS values you are warned against adding new applications or changing the version of frequently used software. This could result in a significant rise in the paging rate.
