  First off, you can try and figure out if its the client (R) or the 
server (your X-windows display server).

  Can you connect to your problem machine from another host (preferably 
one with a different Linux distro, or different X server) and run R, 
sending the graphics over the network. Does it still cause your problem 
machine to go slow? Then its something on the client side.

  If that works fine, then its something to do with the X server on the 
problem machine. Or an interaction term between client and server!
