Evaluating the storage subsystem
Two useful counters in the PhysicalDisk category of performance objects are:
% Disk Time -Displays the percentage of elapsed time that the selected disk drive is busy
servicing read or write requests. If Disk time is higher than 60%, a bottleneck condition is
developing.
Avg. Disk Queue Length -Displays the average number of read and write requests that were
queued for the selected disk during the sample interval.
