Hi

I am testing a few services on two red hat servers, i was wondering would stopping x windows on the server improve performance and speed? and what is the best way to do this i.e. chkconfig it?

Thanks in advance

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).

Huge thanks.

Was looking for that to install Nvidia latest drivers.

Again thanks
