    Much like a cat can stretch out and somehow occupy an entire queen-sized bed, Linux will happily cache your file system as long as there is available memory.

      Note for the “unused RAM is wasted RAM” people, in the description of earlyoom:

      Why is “available” memory checked as opposed to “free” memory? On a healthy Linux system, “free” memory is supposed to be close to zero, because Linux uses all available physical memory to cache disk access. These caches can be dropped any time the memory is needed for something else.

      So yeah, there’s a difference.
