It's probably due to DRI acceleration often not being turned on by
default in Debian's X. Probably depends on your video card/setup.
At a command prompt try typing 'glxinfo' and look for:
direct rendering: No
Try and get that to say "Yes".
Note this is just for displaying graphics; r.mapcalc etc. should be
running much faster on the faster machine.
