Because an AppServer running in state-reset operating mode dedicates an AppServer agent to each client connection, the connected client is guaranteed of having each request handled immediately by the AppServer. Assuming that the general process load on the AppServer platform is light enough, this means that the client can expect relatively fast response time from the AppServer.
However, throughput in a state-reset connection tends to drop as client load increases, because the number of dedicated AppServer agents available to handle client connections is necessarily limited by the number of AppServer agents that can be started on the AppServer machine.
