[racket] executable speed estimate?

Where can Racket be expected fall in comparison with other languages in 
executable speed?

I'm looking at C-Ada-SBCL Lisp-Clojure-Java-Python-Ruby as a kind of a 
rough map.  I checked speeds reported by 
http://shootout.alioth.debian.org/, but no Scheme language seems to be 
listed.

My rough guess is that it would fall about level with Clojure, but 
that's purely based on both being JIT compilation languages of a similar 
form.   The Guide didn't seem to help, though it did give hints on how 
to make ones programs more efficient.
