Thx!

Quit normal. If you study your own picture you will notice that must of the consumed RAM is cached.
You can easily confirm this by:
free && sync && echo 1 > /proc/sys/vm/drop_caches && free

Free memory on *nix is the sum of free memory + buffers + cached. All memory not allocated for running processes is used as disk cache so you cannot use the value of free memory as a metric to conclude whether the system is memory constrained or not.
