If you want to adjust the priority of a program before you start it, you could use the nice command, just like in UNIX: $ nice program3. All process when spawned, they are assigned a priority based on a numeric value called as "nice value". The priority of a process denotes how much processor time allocated to that process. There are 40 niceness values, with –20 being the highest and +19 the lowest. Most system-started processes use the default niceness of 0.
