It would be interesting to have the article author run the lisp code on their machine for a real comparison - would be very interested to see the results. My machine is a Linux (Ubuntu) laptop. I just sent an email to the author with the common lisp code - we'll se if he's interested enough to check.

It seems like he did. (Or may be someone else's. I didn't check the repo.) Common Lisp is the second slowest on his results table.
