If you do not want to limit CPU usage set the value to 0. To determine a value, take the number physical cores and multiply it by 100. For example, on a quad core system (4 * 100 = 400)
there is 400% available. To limit a server to using half of a single core, you would set the value to 50
. To allow a server to use up to two physical cores, set the value to 200
