Note

Be careful when making this measurement since the amount of foreground applications that are open drastically influences what you see in your results.

Also, most of the 3D Open GL screen savers can place unnecessary strain on your server when they are used. These screen savers could be the cause of the problem and should not be used.

Other checks using Performance Monitor:

Object: System

Counter: Processor Queue Length

A sustained processor queue length greater than 2 generally indicates a processor bottleneck.

Object: Processor

Counter: Interrupts/sec

A dramatic increase in this counter value without a corresponding increase in system activity indicates a hardware problem (typically, a failed adapter).

Object: Processes (_Total)

Counter: %Processor Time

If more than a couple of processes are contending for the majority of the processor time, a faster processor or an additional processor should be considered.

You can also use TME 10 NetFinitys System Monitor to display the CPU load as per Figure 112 on page 136. Refer to 6.6, ªSystem Monitorº on page116 for more information.
