An in-server frequency control apparatus includes a preliminary grasp unit which preliminarily grasps a start of a service requiring low delay in a server and grasps termination of the service by a predetermined method, and an operating frequency change unit which changes an operating frequency of a CPU as a target to be controlled, which is a CPU allocated in advance to a receiver of the service in the server, at the time of the preliminarily grasped start of the service and at the time of the termination of the service. The operating frequency change unit makes the operating frequency of the target CPU higher than a predetermined value at the time of the start of the service and makes the operating frequency of the target CPU lower than the predetermined value at the time of the termination of the service.
