Abstract
An installable performance accelerator for computer network distributed file systems is provided. A cache subsystem is added onto, or plugged into, an existing distributed file system with no source code modifications to the operating system. The cache subsystem manages a cache on the client computer side which traps or intercepts file system calls to cached files in order to obtain an immediate and substantial performance increase in distributed file system performance. Additionally, a refresh agent may be installed on the server side to further speed up cache accesses.
