Oracle Solaris 11 allows us to change the priority of processes using the priocntl command either during the start of the process or after the process is run.
This recipe requires a virtual machine (VirtualBox or VMware) running Oracle Solaris 11 with 2 GB RAM at least. It is recommended that the system have more than one processor or core.
