The results are more or less in line with what I would have expected, except for SBCL and Luajit, which I would have expected to be much faster.

The Lisp code is terrible performance-wise and written by someone who obviously doesn't know Common Lisp very well.

Look at Steve Losh's comment here for something a lot better. My own (further) improvements put SBCL performance in the same order as Julia.
