Introduction Firebird uses a page cache to hold pages in memory. It is much quicker to retrieve pages from RAM than to go out onto pages. The page cache is the intermediate between the "working" parts of the database and the disk. When initially started, Firebird reads the database header page, then the first pointer page of a system until the cache is completely full. When there’s no place to put the next page, Firebird releases the least recently used page - not the first one read, but the one that has been referenced least recently0 码力 | 11 页 | 82.76 KB | 1 年前3
