It also  depends on how "nice"  the process is.  Renicing  is just one
way to make  it behave nicer.  Other issues include  making it take up
less  RAM and  do  fewer disk  accesses.   If you  don't believe,  try
starting "gzip -9 < /dev/zero  > /dev/null" as a niced background job,
and see  if you notice the  difference!  This process  uses little RAM
and no disk access.  After renicing, it isn't noticeable .
