I/O priorities

No change in size, 14:02, 24 April 2016
Corrected a mispelling error, but still there is an important question unanswered, what is HZ?
The higher the value you use, the more I/O time your container will receive.
The mapping from priority to time is the following: if <tt>0</tt> prio corresponds to time slice <tt>t</tt>, than then <tt>87</tt> prio corresponds to time slice <tt>2 * t</tt>. Default time slice value is <tt>HZ/2</tt>. The main criteria for fairness at the moment is that if you set I/O prio of CT 1 to <tt>p1</tt> and I/O prio of CT 2 to <tt>p2</tt>, and <tt>p1 > p2</tt> then CT 1 should do more I/O than CT 2. In simple form the priorities are relative with the higher priority getting more I/O time.
