A computer system includes a plurality of processes which execute processing requests, a control unit, and an all-order distribution unit. When the control unit determines execution of a second processing request with a lower priority order than a first processing request, the control unit creates a divided second processing request based on the second processing request in accordance with a division size determined in advance. The all-order distribution unit determines an execution order of one or more processing requests including at least one of one or more divided second processing requests corresponding to one or more second processing requests and one or more first processing requests, and respectively causes the plurality of processes to execute the one or more processing requests in the determined execution order.
