Abstract
One aspect of the invention is a method for load balancing in a distributed object system running on a network comprising a plurality of computers (42, 44) including a first computer (44) wherein the computers (42, 44) are operable to access a plurality of shared objects in a distributed object system. The method comprises instructing an object comprising a part of an application process (50) running on the first computer (44) to record at least one performance statistic in response to a message directed to the object. The application process (50) comprises a multi-threaded process and includes a statistics thread (54). Periodically, at least one performance statistic is obtained using the statistics thread (54) and that performance statistic is sent to a local agent process (48) running on the first computer (44). The performance statistics are relayed to a workload service (46) running on a second computer (42) connected to the network. A new distributed object is instantiated in the memory of one of the plurality of computers (42, 44) based upon performance statistics maintained by the workload service (46).
