When Im benchmarking I make sure X picks up fonts fixed and cursor from the 
correct fonts directory (I.e. don't use xfs), switch to run level 1 and get X 
and the app up (.xinitrc file). Something like

RL#1_%1 su root
ROOT> exec xinit

with .xinitrc having 

exec /usr/bin/gears or something. 

As has already been mentioned benchmarking on a time-sharing machine is 
always tricky. When were benchmarking numerical codes on linux we always goto 
rl#1 (of course those codes only have terminal output so its a damn site 
easier). If we don't we simply don't get consistent results.
