Performance Statistics
Viewing System Utilization
System utilization lets you view:
o the current utilization of the CPUs
o the current utilization of your system memory
o Run Queue displays the current number of active processes waiting on scheduling. If
this number is high, you may have users running computing jobs and not just file
serving on the solution. This can adversely affect performance.
o a table displays the amount of memory in the NAS server and the number of CPUs.
