INFORMATION PROCESSING SYSTEM AND RECORDING MEDIUM TO FACILITATE READING DATA FROM A LARGE-CAPACITY STORAGE UNIT THROUGH A DATA BUFFER

摘要

An information processing system which has a disk buffer 53 for temporarily storing a plurality of data pieces read from a disk unit 6, a block processing order determination module 55 for detecting from a processing request for requesting a plurality of data pieces stored on the disk unit 6, the data piece matching the data stored in the disk buffer 53 among the data pieces requested in the processing request and determining the read order of the match data piece and the remaining data requested in the processing request so as to read the match data piece preceding the remaining data, and read means for reading the match data piece from the disk buffer 53 before reading the remaining data into the disk buffer 53 from the disk unit 6 in accordance with the read order determined by the block processing order determination module 55.
