Linux will use memory that is not needed for programs for buffers and disk cache. This tends to speed up operations, especially disk access if what you want is still in the cache. This is a better then letting memory sit unused. The second line of the free command shows how much is used by programs, and how much can be freed for program use. Freeing up memory used for disk cache is normally fast, and buffers not too much slower. Mikkel -- Do not meddle in the affairs of dragons, for thou art crunchy and taste good with Ketchup!
