it's not lightning fast, but i don't see the long gc pauses. to check it:

(progn
           (sb-alien:define-alien-variable gencgc-verbose sb-alien:int)
           (setf gencgc-verbose 2))

it'll print to the inferior lisp buffer when running through slime.

also make sure logging is not interfering, because the X server can
use up your machine when scrolling 10 lines/sec in an term window...
