I have a machine dedicated to only one function, but the machine lacks RAM, and I've ruled down a small performance issue to a lack of RAM. I run ubuntu-server, and the only things I had to apt-get was ia32libs and mono for another program that uses the internet. Other than that, I don't use anything else on it. What processes can I safely disable, and/or completely uninstall, without negatively affecting the running of my system?
If I need to post a list of my processes, how can I do it via terminal?
