Compilation Speed

I have this code:
http://rghost.net/4410616

And it kills SBCL. But if I replace my-lst with

(defmacro my-lst (&rest xs)
  `(list ,@xs))
it compiles much faster.

compile your code first then run it.
Java also compiles code, but compilation speed isnt a problem, because that has JIT and knows about "Hot Spots". This leads to conlusion, that from perfomance point Java superior.
