According to the some resources I have read, the process with low nice value has more priority. Because it has more priority, CPU allocates more time for that process.
However, it sounds a little bit weird because priority value of a process is calculated by summing nice value with 20.
PR = NI + 20. This can be seen easily with the command top
According to this formula, the processes with higher nice values have higher priorities, but some resources says that the process with low nice value has more priority.
Which one is true ?
