Estou usando o ramnode e, de vez em quando, recebo um e-mail para reduzir minha média de carga. No meu servidor, instalei apenas o Java, o Glassfish e o vncserver. Eu mantenho o vncserver desligado sempre, a menos que eu precise disso. Eu também parei de postfix. Aqui está uma foto da parte superior:
