The background initialization rate, congurable between 0% and 100%, represents the percentage of the system resources
dedicated for running the background initialization task. At 0%, the background initialization has the lowest priority for the controller,
takes maximum time to complete, and has the least impact to system performance. A background initialization rate of 0% does not
mean that the background initialization is stopped or paused.
At 100%, the background initialization is the highest priority for the controller. The background initialization time is minimized and has
the most impact to system performance.
