===> 위의 빨간색으로 되어 있는 것은 상세점검(사용확인)을 해보셔야할 것들이구요.
전체적으로 서버가 느린 원인은 불필요한 데몬들이 거의 모두 사용되고 있는 탓인것 같습니다.
불필요한 프로세스들은 서버의 자원들을 낭비하게 되죠.
간단이 님의 서버용도로 보아,,,atd, rpc.statd, portmap등(정확한 서버용도와 환경을 알수없기에....대부분 불필요할 것 같지만,,이정도)이 서버자원(CPU, MEMORY등)을 낭비하고 있는 것 같습니다.
그리고, 서버로 사용되고 있는 리눅스라면,,, X관련 프로세스들은 모두 죽이시는 것이 좋을 것 같네요...
님의 서버에서 현재 가장 많은 자원을 낭비하는 프로세스는 X와 관련된 프로세스인것 같습니다.
그리고, 위의 빨간색 포트들은 분명한 용도가 없다면, 보안상 해킹의심을 해보아야하는 것입니다.
그럼...20000
