Research questions the validity of the System:Processor Queue Length Counter At low utilization, the Processor Queue Length
can be a relatively high number

Interpreting NT Queue Length Measurements
The validity of the System:Processor Queue Length Counter At low utilization, the observed Processor Queue
Length can be a relatively high number Instantaneous Counter (i.e., sampled value) Application of Heisenberg Uncertainty Principle:
measurement tool can get in the way of the measurement data
e.g., dmperfss collection thread always observed in the
Running state

The validity of the System:Processor Queue Length Counter
Possible low utilization effect Redesign the thread dispatching
logic in NTSMF 2.2.5 to reduce the impact of the threaded collector Currently, in versions 2.2.3 and 2.2.4, all
collection threads (one per Perflib DLL) are dispatched at one time
In version 2.2.5, collection threads will be dispatched in sequence
