James,
>From the following M$ Kbase http://technet.microsoft.com/en-us/library/cc768048.aspx * System : Processor Queue Length. Oddly enough, this processor counter shows up under the System object, but not without good reason. There is only 1 queue for tasks that need to go to the processor, even if there is more than one CPU. Thus, counter provides a measure of the instantaneous size of the queue for all processors at the moment that the measurement was taken. The resulting value is a measure of how many threads are in the Ready state waiting to be processed. When dealing with queues, if the value exceeds 2 for a sustained period, you are definitely having a problem with the resource in question. So I would say that a constant value of 40 to 50 would be an issue. Here are some guidelines that are utilized in our RAP ( rapid Assessment Programs) for SQL from Microsoft Premier Engineers. System Processor Queue Length < 4 per CPU For standard servers with long Quantums <= 4 per CPU Excellent < 8 per CPU Good < 12 per CPU Fair So with your 16 CPU ( assuming a QUAD, Quad Core Server, the value you are looking to be under is 64, which you are. So this might defintely be oks here. Z Edward E.

I am using Citrix EdgeSight 5.3 to measure this, if it makes any difference. My Processor Queue Length is regularly up to 40 or 50.
