I dont understand this. When
free -m show this:
total used free shared buffers cached Mem: 15334 14025 1308 0 258 10918 -/+ buffers/cache: 2848 12485 Swap: 953 0 953
Does it mean I've got 1.4GB Free as per line 1 or 12GB Free as per Line 2?
I have Linux + Nginx + php-fpm + Mysql + Memcached
I understand that the 1.3GB is the free unused memory but if we remove the buffer usage, I actually have 12GB of Free memory on my vps. Does it mean that 16GB for my vps is way too much than what I need and I am wasting it on a big machine since it has 12GB free? Or looking at Line 1, do I take it as since the buffer is using a lot memory which means my machine still benefits from a lot of ram since buffer usage means faster response?
