A cache control apparatus is provided in a computer system including an access source and a storage apparatus. This device, based on I/O status information, which is information denoting the I/O status in accordance with an I/O command from the access source, determines whether or not the I/O performance from the access source drops. In a case where the result of this determination is affirmative, the cache control apparatus changes a cache utilization status specified from cache utilization status information, which is information denoting the cache utilization status related to a cache area, to a cache utilization status that improves I/O performance.
