This paper presents the design, simulation and performance evaluation of a novel reordering write buffer for Log-structured File Systems (LFS). While LFS provides good write performance for small files, its biggest problem is the high overhead from cleaning. Previous research concentrated on improving the cleaner’s efficiency after files are written to the disk. We propose a new method that reduces the amount of work the cleaner has to do before the data reaches the disk. Our design sorts… CONTINUE READING
