Sorry.  I just saw the posted Common Lisp code.  What is the most
optimal way to execute this code?  Is there a particular lisp
implementation that is faster than another?

Actually, due to a misunderstanding of what he asked for, the code didn't do what the other implementations did. It found *unique* words (as in, only had a count of 1) rather than all *distinct* words and their count. I realized this a while ago and re-wrote it. So, use the attached version rather than the earlier one.

I recommend SBCL. Just fire it up and type (load "/path/to/ dicttest.lisp"), and it will load and compile the file. Then type (find-word-counts "/path/to/filename"), and you should get the result in a small fraction of a second. To find out how long it takes to execute, use (time (find-word-counts ... )).

As I mainly did this as an exercise, I didn't profile or optimize it at all, though sbcl does provide two different profilers and several ways to ask the compiler to perform various optimizations.
