System\Context The combined rate at which all processors on Switches/sec the computer are switched from one thread to another. Context switches occur when a running thread voluntarily relinquishes the processor, is preempted by a higher priority ready thread, or switches between user mode and privileged mode to use an executive or subsystem service. High rates of context switching can result from inefficient hardware or poorly designed device drivers or applications. Memory Performance Notes Memory\Pages/sec Pages/sec is the rate at which pages are read from or written to the disk in order to resolve hard page faults. This counter is a primary indicator of the kinds of faults that cause system-wide delays. Memory\Available Available megabytes is the amount of megabytes (MB) physical memory, in megabytes, immediately available for allocation to a process or for system use. Paging File\% Usage The amount of the page file instance in use in percent. Network Performance Notes Server\Error System The number of times an internal server error was detected. Unexpected errors usually indicate a problem with the server. Server\Work Item This occurs when no work item is available or Shortages can be allocated to service the incoming request. A work item is the location where the server stores a server message block (SMB). Work item shortages might be caused by an overloaded server. Server\Blocking Requests The number of times the server has rejected Rejected blocking SMBs due to insufficient count of free work items. This counter indicates whether the MaxWorkItem or MinFreeWorkItems server parameters might need to be adjusted. Server Work Queue length is the current length of the Queues\Queue Length server work queue for this CPU. A sustained
