Just a limited point based on my understanding of "Buf" in
top's display . . .

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 = 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.
