Solaris File System Caching

The Proxy Server cache is not stored in random access memory. Accesses to files are made to the file system each time a document is extracted from cache. You might want to consider using Solaris file system caching to pre-load the Proxy Server cache into memory. References to cached files are then extracted from memory rather than from the file system.
