My current disk queue length is 0 and did stay 0 for a 10 minute test on the performance monitor. The % Disk time is very low as well so I am assuming by this that the problem may not be disk related. As I have said no one process will be using an enormous amount of resources at any given time. Are there further tests I can run to help determine if my machine is simply getting over worked and needs to be replaced by something bigger and better?
