A method and system for processing active AFP sessions by a multithreaded file system process. The file server is coupled to entities on a network, wherein an open AFP session is created when the file server and an entity on the network establish communication, and an active AFP session is created when an AFP session has a pending request. The method and system comprises monitoring the file server for active AFP sessions. When a first active AFP session having at least one AFP request becomes available, the method and system assigns a first one of the threads to the first active AFP session for processing. The method and system preempts the processing of the first active AFP session by the first one of the threads when additional active AFP sessions are available so that the first one of the threads becomes available to process additional active AFP sessions, whereby equal processing time is provided to each one of the active AFP sessions.
