I own a Raspberry PI model B with 512MB of RAM. I am not running any graphical application on it. It just run a few services and when I need to administer it I do that via SSH.
I see that my
/boot/config.txt file contains the following line
but since I am not using anything graphical at all it feels a bit of a waste. At the moment my system is not memory hungry, but I don't foresee I'm going to attach a screen to it so I'd like to have a memory split optimised for my use.
What is the optimal split for my situation?
