The efficient performance of prefetching of data prior to the reading of the data by a program. A prefetching apparatus, for prefetching data from a file to a buffer before the data is read by a program, includes: a history recorder, for recording a history for a plurality of data readings issued by the program while performing data reading; a prefetching generator, for generating a plurality of prefetchings that correspond to the plurality of data readings recorded in the history; a prefetching process determination unit, for determining, based on the history, the performance order for the plurality of prefetchings; and a prefetching unit, for performing, when following the determination of the performance order the program is executed, the plurality of prefetchings in the performance order.
