SBCL (and it's one of the fastest Common Lisps out there) ran MCCLIM at glacial speeds in my n270 netbook, kinda like a busy Pentium MMX running Windows 98 where you could see Win32 controls redrawing themselves. OTOH, GNU Emacs' multithreading sucks, but at least the UI it's miles ahead on responsiveness.

One Lisp REPL doing stuff and GNU Emacs is completely dead as long as the Lisp REPL runs that Emacs Lisp code. It's not even slow, it just is completely non-responsive.
