PROBLEM TO BE SOLVED: To satisfy a requirement that, in the case that a plurality of peripheral devices are connected, a method and a device are required for dynamically adjusting a buffer size to achieve the best performance as a whole. SOLUTION: A buffer management device comprising a data processing device 30, a plurality of peripheral devices 60 connected to the data processing device 30, a plurality of device drivers 32a for controlling the input/output of data, and a buffer management part 40 for managing a buffer size performs initial processing for determining whether or not the buffer size according to information concerning the buffer size declared from the specific device driver 32a of the plurality of the device drivers 32a can be secured, and changes the buffer size dynamically according to the proportion of the throughput of the specific device driver 32a to the throughput of an operation in the whole device driver 32a.
