How many actually use the powerfull Unix renice possibilities to control what process gets less or more processing time over other processes?
How many really know what is the process or PID?
How easily people can adjust what process has higher/lower priority?



We all sometimes get times when one application eats all our multicore CPU time and other applications starts to crawl. Then we are just trying to close other applications as we can think they are not working or we want to close the application what eats all the CPU time as we want to use as well other applications. Or we simply step up from the computer to let it work as it is so slow to use other applications.

Long time ago there was invented a renice program what allows user to tell to operating system (like Linux kernel) what program has priority over others and how high or low the priority is.
In Unix systems there is a scale from -20 to 19 or 20. The 0 is the default level where every program runs if not otherwise configured. -20 is higest possible priority and 19 or 20 is lowest level of the priority.

The current System Monitor does not allow easy priorisation as it shows all the process from the current user. It already show the icons of the running application programs from all programs. But what if we could just simply see only them and drag them up/down on the scale and see on what level they are while compared to others?
