This architecture removes the need for a dedicated server process for each connection. A dispatcher routes various incoming NETWORK session requests to a shared server processes pool. An idle shared server process from a shared pool of server processes CHOOSES a request from a common queue, which means a small number of shared servers can do the same amount of processing as many dedicated servers.
It is because of the amount of MEMORY required for each user is comparatively small, less memory and process management are required, and more users can be SUPPORTED.
