<desc>The <em>nice</em> value of a process is used to adjust its priority.</desc>
</info>
<title>What is the <em>nice</em> value of a process?</title>
<p>The priority of a process determines the share of time the process is
alotted on a system's one or more processors (CPUs or cores). A <em>nice</em>
process, or one with a higher nice value, concedes priority to other processes.
Adjusting the nice value will increase or decrease the scheduling priority.</p>
<p>The lower the nice value, the higher the priority of the process. The nice
value ranges from -20 (low nice, higher priority) to 20 (lower priority). The
default value of nice is usually 0.</p>
