Messaging system to avoid performance degradation

Distributes the message server, the response timeout is held for each of the target allocation threshold, such as another time or number of connections the server, the method determines that the processing performance degradation when in excess of the threshold value, processing of the subsequent server to detect the performance degradation at high speed. In addition, by identifying the server group treated performance degradation from the correlation Cooperative processing between the server when the distribution server is decreased processing performance, distributed to the distribution server is not lowered processing performance of the message server, the availability of the system improves.
