Is there any way to boost an Ubuntu Server's performance? I feel it a bit laggy when hosting a game server on it, unlike other servers. Do you think installing a desktop environment will decrease the server's performance?
Currently I only have an FTP service installed, nothing else. (I use SSH to connect to it.)
VM specs:
⠀OS: Ubuntu Server 14.04
⠀CPU: Dual Core 2.13GHz (2 processors)
⠀RAM: 4GB
⠀Disk: 40GB
