rxvt-unicode uses the wonderful optimization of not really caring
whether everything gets displayed. As a test, simulate some command
that produces output that can't actually be read -- like from a noisy
makefile, the non-error output of TeX, or an accidental `find`:
find / | sed 10000q > ~/find10000
time cat ~/find10000
uxterm takes 2.6 seconds to display text I can't possibly read.
urxvt finishes instantly, only taking 0.04 seconds of wall time.
st takes 50.1 seconds.
Obviously, this isn't the primary use case for a terminal emulator. But
in a term with scrollback, sometimes it's quicker to just dump the data
and scroll back up to the part you care about. And if the interesting
portion is the tail, all the better if it finishes instantly.

I used:
#define FONT "-*-terminus-medium-r-*-*-16-*-*-*-*-*-*-*"
If you're on the 'xft' branch, you'll need a different format, e.g.:
#define XFT_FONT "Bitstream Vera Sans Mono-13"
