Note that the "alternative" Lisp SBCL and Java 7 programs both outperform Fortran. Of course I agree with you on wtf-moments. WTF makes Ruby take an hour, and SBCL take 10 seconds? That's two orders of magnitude! But no matter, I imagine a more clever Ruby programmer could reduce that, or just call out to a native library.

No, since we assume human intelligence here. :P As the Graphics Programming Black Book puts it in the Chapter 1 title, "The Best Optimizer is between Your Ears". > When is a Ruby program fast? When it's written in C ;-) I'm going to use this one.

    I've spent enough time asking for programs for the benchmarks game in Ruby forums, to start to doubt whether the "more clever Ruby programmer" will ever come forward ;-) Maybe "a more clever Ruby programmer" always drops-down to C? Maybe there's only a more clever Rails programmer :-)
