Hi,

I am trying to analyze memory usage on my system.
As first step I am monitoring /proc/meminfo.
Surprisingly I see Mapped value is more than Cached.

So in which case is it possible to have Mapped more than Cached ?

your apps mmap() less than the amount of files content that are cached
through normal read() AFAIK
