Figure 4-1. Response Time as a Function of CPU Utilization

A rundown of the global performance indicators for \NODEA (Example 4-4) shows that the

processor load balance on the system is poor and that there is excessive disk queuing.

The cache performance, with an average cache hit percentage of 83.2, is also

deficient. However, the overriding problem on this node is a serious shortage of

memory, as indicated by the node swap rate and the memory subsystem performance

score (discussed later).
