I wouldn't worry so much about xterm, gnome-terminal and konsole are far 
worse in terms of performance.

I recently ran a couple of tests (which is why I noticed the xterm mark), 
just a relatively noisy rpmbuild of an application. On my IBM T40 the 
build times on otherwise idle box, and completely reproducable, give or 
take couple of seconds:
xterm:		~1m 20s
gnome-terminal: ~1m 40s
konsole:	~1m 40s

Building on a virtual console, redirecting output to /dev/null or a file 
were basically ~1:20 all. That's an awfully lot of time wasted waiting for 
software to build which lot of us do all the time :-/

For cat it's much more dramatic (obviously):
time cat /usr/share/mime-info/gnome-vfs.keys on
virtual console:~0.5s
xterm:		~3.5s
gnome-terminal:	~6.5s
konsole:	~10.5s (not only is it slow but also corrupts the 
		terminal leaving garbage on screen)

Tests done on RHL 9'ish box, FWIW.
