PROBLEM TO BE SOLVED: To improve the throughput of an I/O control system for optimizing an I/O request processing sequence in the I/O control system. SOLUTION: This computer program includes checking how many and how sequenced I/O requests are lined up in the queue of an I/O control system, and which storage region is pertinent to the I/O destination of each of the I/O requests, and calculating the number of I/O as the number of the I/O requests as the I/O destinations for each of two or more storage regions as the I/O destinations of a plurality of I/O requests lined up in the queue among a plurality of storage regions based on the check result, and rearranging the sequence of the plurality of I/O requests in the queue so that the I/O requests whose I/O destinations belong to the storage regions with the larger number of I/O can be sequenced more earlier.
