You could run the Xvfb virtual frame buffer Xserver and set DISPLAY to
that server. But I doubt that this would speed up anything, the
additional memory consumption would rather slow down everything, IMHO.

For that "null port" you can use the Xvfb (X Virtual Frame Buffer)
server.

Xvfb has shipped with every X Consortium release since X11R6(.0).

If your vendor doesn't ship X11R6.x, I encourage you to call your sales
office and ask them for it. If your vendor ships X11R6.x but doesn't
ship Xvfb I encourage you to do likewise.

Otherwise you can build it from source, which is available at
ftp://ftp.x.org/pub/R6.3/tars.

	You can try set -iconic flags at start. It is not full redirect,
	but very easy:-)

I think the only way to do that is giving an option to the program, if
it has this option. XV (a program to display jpgs, gifs, etc...), for
example, has an option not to show its window. Read the man page for the
application if provided...
