This may sound like a silly question, but what terminal emulator are you using? I found that xfce's Terminal gave me awful performance, taking a really long time to redraw, but xterm and roxterm sped things up a lot. I think for me part of this is related to the nvidia driver breakage with the new Xorg. Can you see if you can duplicate that behavior with xterm?
