If "cached" means "Buf" in top's output, my understanding of Buf is that it is not a distinct memory area. Instead it totals the buffer space that is spread across multiple states: Active, Inactive, Laundry, and possibly Wired(?). In other words: TotalMemory =3D Active+Inact+Laundry+Wired+Free. If Buf is added to that then there is double counting of everything included in Buf and the total will be larger than the TotalMemory. Also Inact+Buf+Free may double count some of the Inact space, the space that happens to be inactive buffer space. I may be wrong, but that is my understanding. =3D=3D=3D Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
