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).
