changing a process' priority...
from the gui:
Run the system monitor as root with
Then under the "view" menu move the radio button to "All processes"
Then you will see all users processes and can change their priority.
from the command line:
First find your processes PID (Process ID) with
pidof like so:
It will return the PID of the given process, usually a four to five character number. Then run
renice priority processes-PID
priority with the priority you want (
-20 being the highest and
+20 being the lowest) and
process-PID with the PID you got earlier.
renice is used to change the priority of a running process, if you want to start a process and change it's priority you use
nice priority name-of-process
priority with the priority you want and
name-of-process with the name of the process you want to start.
Note: In order to give a process a negative priority you must have root access.
