A peripheral subsystem having a plurality of buffered control units enables access to a plurality of devices from a plurality of hosts. Because loading can vary between the various buffered control units, the present article shows a dynamic procedure for balancing the buffered control unit activity for maximizing the efficiency of the peripheral subsystem. Balancing is based upon depth of work queues for the various buffered control units. Threshold detection is employed. Balancing occurs during a pause in device activity.
