MemTotal: 2016688 kB MemFree: 1528748 kB Buffers: 424 kB Cached: 140060 kB SwapCached: 0 kB Active(anon): 329884 kB Inactive(anon): 4 kB Active(file): 23368 kB Inactive(file): 47328 kB Unevictable: 0 kB Mlocked: 0 kB SwapTotal: 1542232 kB SwapFree: 1542232 kB Dirty: 64 kB Writeback: 0 kB AnonPages: 260100 kB Mapped: 85036 kB
Usually, Cached - tmpfs ~= Active(file) + Inactive(file). tmpfs file isn't droppable.
We should see Active(file) + Inactive(file) (= 70696kB) instead Cached. In addition, drop_cache sysctl can't drop Mapped memory.
Then, this value isn't so wonder value, IMHO.
