A command process load balancing system performs load balancing of received commands among a number of server processes to resolve access contention for virtual software resources. These contentions are resolved through a history recording unit that records a history including contents of a processed command and a response time of a process for the command into a history database. A prediction unit predicts, in a case where a set of commands to be processed is assigned to a server process, whether or not a load that is equal to or higher than a reference value is applied, on the basis of the history recorded in the history database. An assigning unit assigns at least one command included in the set of commands to be processed to a different server process, in accordance with prediction that a load that is equal to or higher than the reference.
