ENHANCING METHODS OF SEARCHING PERFORMANCE BY USING FILE COMPRESSION BASED ON BLOCKS

摘要

If being that significantly, application program discontinuously reads or writes big file when the auxiliary storage device and operating system of the page (heat exchange amount between I/O amounts), whole system includes that operating system is to influence. Thereby reason, compresses on Documents Logical and reduces I/O amounts and carry out the method for priority system performance and significantly decrease I/O amounts using. The present invention relates to it is a kind of provide effective high-performance searching method access file search and obtain data. The method which irons performance is improved the present invention provides a kind of, includes the following steps: that the disk for only writing compression space carries out compression specific block unit when data are to write in file in data; And read only that compression specific block unit is without reading all files, block is released after the compression of the file search data read access data. ;The 2015 of copyright KIPO submissions
