“Comparisons are odious” as my Mum used to say, but I hope this little comparison doesn’t pong too much. I have a range a little competitions of my own, a language bench mark, based on “The Computer Language Benchmarks Game” (http://shootout.alioth.debian.org), between IronPython and F#, with measurements for C# thrown in as a kind of control group. I would have liked to chuck in the new IronRuby language too, but I had problems finding a current release. This was largely inspired by the benchmarks Ben Jackson posted to the hubfs.net (http://cs.hubfs.net/forums/thread/3196.aspx), thanks Ben!
Now obviously as an author of a book...
