EvtQueue, EvtQFast, EvtQLarge, and EvtQSlow. These folders within the Altiris folder structure are the lifeblood of data processing for your Notification Server.
One might wonder if EvtQueue is more important than EvtQFast, EvtQLarge, or EvtQSlow? Or could EvtQFast get preferential treatment? What happens when multiple NSE files are captured at the same time - does one queue get a priority over any other and if so, what is that priority?
Well, in the interest of fair play, the Notification Server does not play favorites. No queue has priority over another. Each one has been assigned one or more processor threads, (with the exception of EvtQLarge), and the remaining queues all process concurrently. The default threads for each queue are different however. EvtQFast has 10, EvtQueue has 3, and EvtQSlow has 1.
