4.2 File System Types

4.2.4 Cachefs

The cache file system, cachefs, lets you use a disk drive on a local system to cache frequently used data from a remote file system or CDROM. The cache is a temporary storage area for those files. The data is read from the original file system and stored in the cache on the local disk. The next time the file is accessed, it will come from the cache, after first insuring that the original file has not changed. This reduces network traffic and/or increases response time from a slow medium such as CDROM. The cache file system can store files from one or more remote file systems on a local disk. This should be useful in situations where you have enough disk space to set aside for cachefs and where your local machine is fast enough that you don't lose too much time caching the file the first time.
