Abstract
A single transaction technique for a journaling file system of a computer operating system in which a single file system transaction is opened for accumulating a plurality of current synchronous file system operations. The plurality of current synchronous file system operations are then performed and the single file system transaction closed upon completion of the last of the file system operations. The single file system operation is then committed to a computer mass storage device in a single write operation without the necessity of committing each of the separate synchronous file system operations with individual writes to the storage device thereby significantly increasing overall sytem performance. The technique disclosed is of especial utility in conjunction with UNIX System V based or other journaling operating systems.
