Processes can be executed concurrently in operating systems; they can be created dynamically and then terminate, i.e. process creation and termination are required for program execution. However the costs involved in process creation and termination make this procedure expensive. This procedure expensive, thus degrading the performance of program execution. To solve this problem, a fast process creation and termination mechanism is proposed. This mechanism is implemented by recycling process resources. In order to improve the efficiency of recycling, the management of preserved process resources for recycling is an important factor. In this paper, we propose an improved resource management method for recycling process resources and an adaptive control mechanism. In the method, only one process resource with a program image is preserved for each program that occurs with high frequency of program execution. The proposed method can reduce the amount of memory consumption for preserved process resources in a concurrent execution environment. We also describe the implementation of the proposed method on the Tender operating system and report the results of our experiments.
