Have you monitored the CPU usage with something like top
? If it is low, like less than 50% with few or no peaks at or above 90-95%, then it will probably not improve server performance. Server performance is often limited by disk & network throughput, so performance improvements shoud be focused on those areas. You can stop the X server gracefully, generally through a desktop control/menu, or ungracefully with Ctrl-Backspace. Your distro may have it configured to automatically restart after being killed. You can force the system to boot into console-only mode by adjusting the runlevel to 3. In /etc/inittab
, find a line near the top of the file that resembles this:
Change the '5' to '3'. Subsequent re-boots will be console-only mode. You can enter runlevel 3 with the command 'init 3
' (as root).
