PROBLEM TO BE SOLVED: To enable performance improvement based on the load distribution of an entire system and to attain improvement in the utilization efficiency of the entire system, even when increasing/decreasing the users of services provided by plural programs in the system in a distributed object environment. SOLUTION: For a server computer 1, for example, the copy of a server object is prepared dynamically during the operation of a server program 12A, transferred onto another server computer 2, for example, of low CPU utilization rate and operated and corresponding to a remote method call from a client computer, remote method calling is made to perform by the copied object. When the number of times of remote method calling to the copied object does not exceed a prescribed number of times within the prescribed time, the utilization efficiency is regarded as being low, and the copied object is automatically eliminated.
