Hi

  The kernel maintains a priority value (sometimes termed the scheduling
  priority) for each thread. The priority value is a positive integer and
  varies inversely with the importance of the associated thread. That is, a
  smaller priority value indicates a more important thread. When the scheduler
  is looking for a thread to dispatch, it chooses the dispatchable thread with
  the smallest priority value.

  A thread can be fixed-priority or nonfixed priority. The priority value of a
  fixed-priority thread is constant, while the priority value of a nonfixed
  priority thread is the sum of the minimum priority level for user threads (a
  constant 40), the thread's nice value (20 by default, optionally set by the
  nice or renice command), and its CPU-usage penalty.

  See  man nice   and    man renice.

    Regards
