Abstract: The present invention relates to the technical field of computer systems with improved response time to a user request in a computer session. More particular, the present invention provides improved response time for a client/server- configuration of Personal Computers in a network as well as for stand-alone computer systems.The inventive concepts provide a `Services Supercharger` layer of programs and information tables, exploiting the capability to start many tasks in parallel, to prepare the execution environment for one or more user sessions and actions within such user sessions, and after session termination, performs epilogue actions only when appropriate.The described concepts realize a solution where the possibility of executing multiple tasks in parallel in a system like OS/2 can be exploited to reduce the response time for individual user requests against the system considerably. These concepts can be applied to stand-alone user workstations and in client/server environments.
