Average disk I/O requests in queue (AverageRequestsInQueue)
This attribute displays the average number of disk I/O requests in the queue and is measured only when the queue is occupied. A high number indicates that system throughput is probably slowing down because of the number of I/O requests for this disk. This can be caused by
- paging and swapping due to low memory
- overloading an I/O controller's capacity
- having most of the heavily-accessed files on the same disk/controller
