LIM reports a host as busy

If LIM often reports a host as busy when the CPU utilization and run queue lengths are relatively low and the system is responding quickly, the most likely cause is the paging rate threshold. Try raising the pg threshold.

Different operating systems assign subtly different meanings to the paging rate statistic, so the threshold needs to be set at different levels for different host types. In particular, HP-UX systems need to be configured with significantly higher pg values; try starting at a value of 50.

There is a point of diminishing returns. As the paging rate rises, eventually the system spends too much time waiting for pages and the CPU utilization decreases. Paging rate is the factor that most directly affects perceived interactive response. If a system is paging heavily, it feels very slow.
