file system clusters data that is sequentially accessed and provides two block sizes to allow fast access to large files while not wasting large amounts of space for small files. File access rates of up to ten times faster than the traditional UNIX file system are experienced. Long needed enhancements

was delivering only 2 % of overall disk bandwidth! 1 2 LOCALITY AND THE FAST FILE SYSTEM The main issue was that the old UNIX file system treated the disk like it was a random-access memory; data was spread all over the place without regard to the fact that the medium holding the data was a disk, and thus had

. For example, the data blocks of a file were often very far away from its inode, thus inducing an expensive seek whenever one first read the inode and then the data blocks of a file (a pretty common operation). 1 2 LOCALITY AND THE FAST FILE SYSTEM Worse, the file system would end up getting quite fragmented

Given the increasing performance of network connections and the slow nature of disk drives, the authors propose a new file system for web proxy servers that cache files on a local disk. This file system, referred to as the cache file system (CFS), utilizes the facts that cached web pages do

in the system can store, cache, or control any block of data. Our approach uses this location independence, in combination with fast local area networks, to provide better performance and scalability than traditional file systems. Further, because any machine in the system can assume the responsibilities of a

This paper presents a new technique for disk storage management called a log-structured file system. A logstructured file system writes all modifications to disk sequentially in a log-like structure, thereby speeding up both file writing and crash recovery. The log is the only structure on disk
