You might be seeing alot of X related slowness, but its not the only thing going 
on... I'd really like to see an argument made for why Nautilus takes a full 10s 
to show my home directory each time (about 40 files/directories) if X is the 
only culprit.  Its just not going to be an easy argument to make (and the cpu is 
not under heavy load).  Why does the entire window not update until its fully 
populated, only part of the list is going to be drawn (and X knows nothing about 
the hidden part of that list).

There are some X slowdowns sure.  Trying to select/copy a large amount of text 
out of the terminal is a good example of what is almost entirely X slowness; the 
scrolling upward is fully smooth if you're not dragging a selection.
