Method and apparatus for managing buffer cache to perform page replacement by using reference time information regarding time at which page is referred to |
摘要 |
A method and apparatus manages a buffer cache. An extended buffer is used to perform a page replacement algorithm using reference time information regarding a time at which a page is referred. Pages replaced through the page replacement algorithm, when re-referred to, may be retrieved from the extended buffer, instead of a hard disk. As a result, write/read operations with respect to the disk are made efficient and the page input/output speed is increased. |
