Disk cache performance for distributed systems

The influence of client and server cache sizes and the number of clients on caching performance is studied through trace-driven simulation. The results indicate that the locality of reference in disk block reference patterns allows relatively small caches to reduce significantly the number of disk accesses required. File server cache performance is significantly different from client cache performance owing to the capture of disk block references by the client caches. The major factor influencing overall miss ratio statistics (actual disk reference frequencies) is found to be the maximum of the server cache size and the size of client caches.< >
