There's no set formula to determine how much cache memory to use, but as a
general rule, a workstation, with mostly very large files, such as for audio or
video editing and playback, graphics or CAD files, can benefit from a large
cache. File servers, with multiple random access of varying file size, generally
have little or no performance improvement with additional cache.
