Do you attribute most of the difference in performance to the OS change or to the implementation change, though? (I'll never use Windows, but I've been considering using Lispworks again on OS X for a few things.) I've always used LW with Emacs in the past, not the LW IDE. I use Aquamacs for almost everything now...and SLIME is great.

What Lisp libs are you using, if you don't mind my asking? I'm trying to figure out why CL-Memcached is slower than freaking PHP and Python for most things (!)
