Some operating systems lower the priority of processes as the processes run over a long period of time. NOAGE, when set to 1, disables priority aging of CPU virtual processors by the operating system. When NOAGE is set to the default of 0, the operating system might lower the priority of CPU virtual processors, as well as other processes, as they accumulate processing time. If your operating system supports priority aging, it is recommended that you set NOAGE to 1.
