The default setings should be ok for a regular user.
There is a safety switch that will turn off optimizing if the cycle`s length is greater then the preset. Setting the optimizing cycle lower will react to boosting mechanism only.
Setting the managing profiles refresh to smaller value speeds up the auto-set class priorities task. Optimizing cycle timing also affects the Anti-LockUp (automatic priority class lowering function) reaction speed.
